 ## Kurzfassung
+
 1. „Ein Link, um ein Buch auf einfache Weise herunterzuladen“ ist nicht immer ein Link zu einem *kostenlosen* Buch. Bitte füge nur kostenlose Inhalte hinzu. Vergewissere Dich, dass sie kostenlos sind. Wir akzeptieren keine Links zu Seiten, die *voraussetzen*, dass man sich mit einer funktionierenden E-Mail-Adresse registriert, um ein Buch herunterzuladen, aber wir heißen Seiten willkommen, die um (optionale) Eingaben von E-Mail-Adressen bitten.
+
 2. Du musst Dich nicht mit Git auskennen: Wenn Du etwas Interessantes gefunden hast, *das noch nicht in einer der Listen enthalten ist*, öffne bitte ein [Issue](https://github.com/EbookFoundation/free-programming-books/issues) mit Deinen Linkvorschlägen.

     - *Bücher*: PDF, HTML, ePub, eine auf gitbook.io basierende Seite, ein Git Repo etc.
     - *Kurse*: Ein Kurs beschreibt Lernmaterialien, die nicht in Buchform existieren. [Dies ist ein Kurs](http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-006-introduction-to-algorithms-fall-2011/).
-    - *Interaktive Tutorials*: Eine interaktive Webseite, die den Benutzer Sourcecode oder Kommandos eingeben lässt und das Resultat auswertet (mit "auswerten" meinen wir nicht "bewerten"). z. B.: [Try Haskell](http://tryhaskell.org), [Try Github](http://try.github.io).

     - *Podcasts und Screencasts*: Podcasts und Screencasts.
     - *Problem Sets & Competitive Programming*: Eine Webseite oder Software, die Dir die Möglichkeit gibt, Deine Programmierfähigkeiten durch die Lösung einfacher oder komplexer Problemstellungen auf die Probe zu stellen, mit oder ohne Code Review und mit oder ohne den Vergleich der Leistungen mit anderen Besuchern der Seite.

 ### Richtlinien

 - Stell sicher, dass ein Buch wirklich kostenlos ist. Vergewissere Dich noch einmal, falls nötig. Es hilft den Administratoren, wenn Du in Deinem PR beschreibst, warum Du der Ansicht bist, dass das jeweilige Buch kostenlos ist.
 - Wir nehmen keine Dateien auf, die auf Google Drive, Dropbox, Mega, Scribd, Issuu oder einer vergleichbaren Upload-Plattform liegen.
 - Füge die Links in alphabetischer Reihenfolge ein. Wenn Du einen fehlerhaft eingefügten Link findest, korrigiere bitte die Reihenfolge und öffne eine PR.
 - Wähle immer den Link der maßgeblichen Quelle aus (das heißt, dass die Website des Autors besser ist als die eines Redakteurs, welche wiederum besser wäre als die einer Drittanbieterseite)
-    + Keine File Hosting Plattformen (inklusive Links zu Dropbox, Google Drive u.ä.)
+    - Keine File Hosting Plattformen (inklusive Links zu Dropbox, Google Drive u.ä.)
 - Ein `https` Link sollte einem `http` Link immer vorgezogen werden -- solange sie auf dieselbe Domain und denselben Inhalt verweisen.
 - Auf Root Domains sollte der abschließende Schrägstrich entfernt werden: `http://example.com` anstelle von `http://example.com/`
 - Wähle immer den kürzesten Link: `http://example.com/dir/` ist besser als `http://example.com/dir/index.html`
-    + Benutze keine URL-Verkürzer
+    - Benutze keine URL-Verkürzer
 - Wähle bevorzugt den Link zur aktuellsten Version anstatt eine konkrete Version zu verlinken: `http://example.com/dir/book/current/` ist besser als `http://example.com/dir/book/v1.0.0/index.html`
 - Wenn ein Link ein abgelaufenes oder selbst-signiertes Zertifikat nutzt oder ein anderes SSL Problem aufweist:
     1. *ersetze ihn* mit seinem `http` Gegenstück, wenn möglich (weil es auf Mobilgeräten kompliziert sein kann, Ausnahmen zuzulassen).

 - Bevorzuge atomare Commits (ein Commit pro Änderung), anstatt größere Commits zu machen. Es besteht keine Notwendigkeit, die Commits vor dem Abschicken des PR zu squashen. (Wir werden die Befolgung dieser Regel niemals erzwingen, da es sich hier nur um die Vermeidung von Unannehmlichkeiten für die Maintainer handelt)
 - Vermerke das Datum der Veröffentlichung im Titel, wenn es sich um ein älteres Buch handelt.
-- Erfasse gegebenenfalls den Namen des oder der Autoren. Eine längere Liste von Autoren kann mit dem Zusatz "et al." gekürzt werden.
-- Wenn das Buch noch nicht fertiggestellt ist und sich noch in Bearbeitung befindet, füge wie [unten](#in_process) beschrieben einen "in Bearbeitung" Hinweis hinzu.
-- Wenn eine funktionierende E-Mail Adresse oder das Einrichten eines Benutzerkontos vor Aktivierung des Downloads erbeten wird, sollten angemessene Hinweise in Klammern angegeben werden, z. B.: `(E-Mail Adresse *erbeten*, nicht erforderlich)`

 ### Formatierung
+
 - Bei allen Listen handelt es sich um `.md` Dateien. Versuche bitte, Dir die [Markdown](https://guides.github.com/features/mastering-markdown/) Syntax anzueignen. Sie ist ganz einfach!
 - Alle Listen beginnen mit einem Inhaltsverzeichnis, in dem alle Abschnitte und Unterabschnitte verlinkt werden sollten. Bitte halte eine alphabetische Reihenfolge ein.
 - Abschnitte nutzen Überschriften der Ebene 3 (`###`), während Unterabschnitte die 4. Ebene (`####`) nutzen.
 
 Folgende Formatierungsregeln sollten eingehalten werden:
+
 - `2` Leerzeilen zwischen dem letzten Link und einem neuen Abschnitt.
 - `1` Leerzeile zwischen der Überschrift und dem ersten Link eines Abschnitts.
 - `0` Leerzeilen zwischen zwei Links.

 ### Hinweise
 
 Während die Grundlagen relativ einfach sind, existiert eine große Vielfalt von Ressourcen in unseren Listen. Es folgen einige Hinweise, wie wir mit dieser Vielfalt umgehen.
 
+
 #### Metadaten
 
 Unsere Listen enthalten einen minimalen Satz an Metadaten: Titel, URLs, Autoren, Plattformen und Zugriffshinweise.
 
+
 ##### Titel
 
 - Keine erfundenen Titel. Wir versuchen, die Titel den Inhalten selbst zu entnehmen; Mitwirkende werden dazu ermahnt, sich keine Titel auszudenken oder redaktionell zu nutzen, falls dies vermieden werden kann. Eine Ausnahme bilden ältere Werke; wenn sie vor allem von historischem Interesse sind, kann das Hinzufügen einer Jahreszahl in Klammern den Nutzern helfen zu bestimmen, ob die Inhalte für sie nützlich sind.
 - Keine Titel, die NUR GROßBUCHSTABEN ENTHALTEN. Titelkapitalisierung ist normalerweise angemessen, aber im Zweifel nutze einfach die Formatierung der Originalquelle.
 
+
 ##### URLs
 
 - Wir erlauben keine gekürzten URLs.
 - Sämtliche Tracking-Codes sind aus der URL zu entfernen.
 - Internationale URLs sollten entsprechend maskiert/escaped werden. Auch wenn Adressleisten in Browsern diese üblicherweise in Unicode darstellen, nutze bitte kopieren & einfügen.
-- Sichere (https) URLs werden immer nicht-sicheren (http) URLs vorgezogen, wenn von der Quelle https implementiert wurde.
+- Sichere (`https`) URLs werden immer nicht-sicheren (`http`) URLs vorgezogen, wenn von der Quelle HTTPS implementiert wurde.
 - Wir mögen keine URLs, die auf Webseiten zeigen, die den angegebenen Inhalt nicht bereitstellen, sondern stattdessen an andere Stelle umleiten.
 
+
 ##### Urheber
 
 - Wir wollen alle Urheber kostenloser Inhalte angemessen nennen, inklusive eventueller Übersetzer!
 - For übersetzte Werke sollte der Autor des ursprünglichen Werks genannt werden.
 - Wir erlauben keine Links für Urheber.
-- Für Sammlungen oder neu zusammengestellte Werke, benötigt der "Urheber" eventuell eine Beschreibung. Bücher von "GoalKicker" werden z.&nbsp;B. als "Zusammengestellt aus StackOverflow Dokumentationen" gekennzeichnet.
+- Für Sammlungen oder neu zusammengestellte Werke, benötigt der "Urheber" eventuell eine Beschreibung. Bücher von "GoalKicker" werden z.&nbsp;B. als "`Zusammengestellt aus StackOverflow Dokumentationen`" (auf englisch: "`Compiled from StackOverflow documentation`") gekennzeichnet.
+
 
 ##### Plattformen und Zugriffshinweise
 
 - Kurse. Insbesondere bei unseren Kurslisten spielt die Plattform eine wichtige Rolle in der Beschreibung des Inhalts. Der Grund dafür ist, dass Kurs-Plattformen unterschiedliche Zugangsmodelle und Angebotscharakter haben. Obwohl wir keine Bücher aufnehmen, die eine Registrierung erfordern, können viele Kurs-Plattformen ohne irgendeine Art der Registrierung nicht funktionieren.

 ##### Buch vs. Kurs
 
 Das ist manchmal gar nicht so leicht zu unterscheiden!
 
 Kurse kommen oftmals mit begleitenden Lehrbüchern, die wir in unseren Bücherlisten führen würden. Kurse bieten Vorträge, Übungen, Tests, Anmerkungen oder andere Lernhilfen. Ein einzelner Vortrag oder Video allein ist kein Kurs. Eine Powerpoint-Präsentation ist kein Kurs.

 ## Με λίγα λόγια
 
 1. "Ένας σύνδεσμος για να κατεβάσω εύκολα ένα βιβλίο" δεν είναι πάντα ένας σύνδεσμος για *δωρεάν* βιβλίο. Παρακαλούμε να συνεισφέρετε μόνο δωρεάν περιεχόμενο. Να σιγουρεύετε ότι είναι δωρεάν. Δεν δεχόμαστε συνδέσμους για σελίδες που *απαιτούν* λειτουργικές ηλεκτρονικές διευθύνσεις για να αποκτηθούν βιβλία, αλλά είναι ευπρόσδεκτες καταχωρήσεις που τις ζητούν προαιρετικά.
+
 2. Δεν χρειάζεται να γνωρίζετε Git: αν βρήκατε κάτι ενδιαφέρον που *δεν βρίσκεται ήδη σε αυτό το αποθετήριο*, παρακαλώ ανοίξτε ένα [Issue](https://github.com/EbookFoundation/free-programming-books/issues) με τις προτάσεις σας για συνδέσμους.
     - Αν γνωρίζετε Git, παρακαλούμε να κάνετε Fork αυτό το αποθετήριο και να στέλνετε Pull Requests (PR).
+
 3. Έχουμε 5 τύπους λιστών. Επιλέξτε την κατάλληλη:
 
     - *Βιβλία* : PDF, HTML, ePub, ένας ιστότοπος που βασίζεται στο gitbook.io, ένα αποθετήριο Git, κλπ.
     - *Μαθήματα* : Ένα μάθημα είναι εκπαιδευτικό υλικό που δεν είναι βιβλίο. [Αυτό είναι ένα μάθημα](http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-006-introduction-to-algorithms-fall-2011/).
-    - *Διαδραστικά σεμινάρια* : Μια διαδραστική ιστοσελίδα που επιτρέπει στον χρήστη να γράψει κώδικα ή εντολές και αξιολογεί τα αποτελέσματα (με το "αξιολογεί" δεν εννοούμε "βαθμολογεί"). π.χ. [Try Haskell](http://tryhaskell.org), [Try Github](http://try.github.io).

     - *Podcasts και Screencasts*: Podcasts και screencasts.
     - *Προβλήματα και Ανταγωνιστικός Προγραμματισμός*: Ένας ιστότοπος ή ένα λογισμικό που σου επιτρέπει να αξιολογήσεις τις προγραμματιστικές σου ικανότητες λύνοντας απλά ή περίπλοκα προβλήματα, με ή χωρίς επιθεώρηση του κώδικα, συγκρίνοντας ή όχι τα αποτελέσματα με άλλους χρήστες.

 ### Σημειώσεις
 
 Αν και τα βασικά είναι σχετικά απλά, υπάρχει μεγάλη ποικιλία στο υλικό που παρουσιάζουμε. Ορίστε μερικές σημειώσεις για το πως να αντιμετωπίσετε αυτή την ποικιλία
 
+
 #### Metadata
 
 Οι λίστες μας παρέχουν ένα ελάχιστο σύνολο από metadata: τίτλους, URLs, δημιουργούς, πλατφόρμες, και σημειώσεις πρόσβασης
 
+
 #### Τίτλοι
 
 - Όχι δικοί σας τίτλοι. Προσπαθούμε να πάρουμε τους τίτλους από τις ίδιες τις πηγές· οι συνεισφέροντες επιβάλλεται να μη εφευρίσκουν τίτλους ή να τους χρησιμοποιούν εκδοτικά αν αυτό μπορεί να αποφευχθεί. Μια εξαίρεση είναι για παλαιότερα έργα· αν είναι παρουσιάζουν κυρίως ιστορικό ενδιαφέρον, το έτος στην παρένθεση προσαρτημένο με τον τίτλο βοηθά τους χρήστες να γνωρίζουν αν τους ενδιαφέρει.
 - Όχι τίτλοι αποκλειστικά σε ΚΕΦΑΛΑΙΑ. Η συνήθης κεφαλαιοποίηση τίτλων (title case) είναι κατάλληλη, αλλά όταν υπάρχουν αμφιβολίες χρησιμοποιήστε την κεφαλαιοποίηση της πηγής
 
+
 #### URLs
 
 - Δεν επιτρέπουμε περικομμένα URLs.
 - Κωδικοί ανίχνευσης πρέπει να αφαιρεθούν από το URL.
 - Τα διεθνή URLs πρέπει να είναι escaped. Οι browsers τυπικά τα μετατρέπουν σε Unicode, αλλά χρησιμοποιήστε αντιγραφή και επικόλληση, παρακαλούμε.
-- Ασφαλή (https) URLs προτιμώνται πάντα αντί για μη ασφαλή (http) urls για τα οποία έχει υλοποιηθεί https.
+- Ασφαλή (`https`) URLs προτιμώνται πάντα αντί για μη ασφαλή (`http`) urls για τα οποία έχει υλοποιηθεί HTTPS.
 - Δεν μας αρέσουν URLs που οδηγούν σε ιστοσελίδες που δεν φιλοξενούν το υλικό που αναφέρεται, αλλά αντ' αυτού οδηγούν αλλού.
 
+
 #### Δημιουργοί
 
 - Θέλουμε να αναφέρονται τα ονόματα των δημιουργών δωρεάν υλικού όπου κρίνεται κατάλληλο, συμπεριλαμβανομένων των μεταφραστών!
@@ -170,18 +179,21 @@
 - Δεν επιτρέπουμε συνδέσμους για Δημιουργούς.
 - Για συλλεγμένα ή επεξεργασμένα έργα, ο "δημιουργός" ίσως χρειάζεται περιγραφή. Για παράδειγμα, τα βιβλία από το "GoalKicker" ή "RIP Tutorial" αναφέρονται ως "`Συντάχθηκαν από documentation του StackOverflow`" (στα αγγλικά: "`Compiled from StackOverflow documentation`").
 
+
 #### Πλατφόρμες και Σημειώσεις Πρόσβασης
 
 - Μαθήματα. Ειδικά για τις λίστες μαθημάτων μας, η πλατφόρμα είναι ένα σημαντικό κομμάτι της περιγραφής του υλικού. Αυτό επειδή οι πλατφόρμες με μαθήματα έχουν διαφορετική προσβασιμότητα και μοντέλα πρόσβασης. Ενώ συνήθως δεν θα προσθέσουμε ένα βιβλίο που απαιτεί εγγραφή, πολλές πλατφόρμες μαθημάτων έχουν χαρακτηριστικά που δεν θα δουλέψουν χωρίς κάποιο τύπο λογαριασμού. Παραδείγματα πλατφορμών μαθημάτων περιλαμβάνουν τα Coursera, EdX, Udacity και Udemy. Όταν ένα μάθημα εξαρτάται από την πλατφόρμα, το όνομα της πλατφόρμας θα πρέπει να αναφέρεται σε παρένθεση.
 - YouTube. Έχουμε πολλά μαθήματα που αποτελούνται από playlists στο YouTube. Δεν παραθέτουμε το YouTube σαν πλατφόρμα, προσπαθούμε να αναφέρουμε τον δημιουργό στο YouTube, που είναι συνήθως υπό-πλατφόρμα.
 - Βίντεο στο YouTube. Συνήθως δεν δεχόμαστε σε ατομικά βίντεο του YouTube εκτός αν είναι περισσότερο από μια ώρα και έχουν δομή σαν μάθημα ή σεμινάριο.
-- Leanpub. Το Leanpub φιλοξενεί βιβλία με διαφορετικά μοντέλα πρόσβασης. Κάποιες φορές ένα βιβλίο μπορεί να διαβαστεί εγγραφή· κάποιες φορές ένα βιβλίο απαιτεί λογαριασμό στο Leanpub για δωρεάν πρόσβαση. Δεδομένης της ποιότητας των βιβλίων και του μίγματος και της ρευστότητας των μοντέλων πρόσβασης του Leanpub, επιτρέπουμε την παράθεση του τελευταίου με τη σημείωση πρόσβασης `*(Ζητείται λογαριασμός Leanpub ή έγκυρο email)*`

 ##### Títulos
 
 - Sin títulos inventados: Intentamos tomar el texto de los propios recursos; se advierte a los colaboradores que, si puede evitarse, no inventen títulos ni los utilicen editorialmente. Una excepción es para obras más antiguas: si son principalmente de interés histórico, un año entre paréntesis adjunto al título ayuda a los usuarios a saber si estos son de interés.

 - No se permiten acortadores de URLs para los enlaces.
 - Los parámetros de consulta o códigos referentes al seguimiento o campañas de marketing deben eliminarse de la URL.
 - Las URL internacionales deben escaparse. Las barras del navegador suelen representar los caracteres en Unicode, pero utilice copiar y pegar, por favor; es la forma más rápida de construir un hipervínculo válido.
-- Las URL seguras (https) siempre son mejor opción frente a las no seguras (http) donde se ha implementado el protocolo de comunicación encriptado HTTPS.

 ##### Plataformas y Notas de Acceso
 
 - Cursos. Especialmente para nuestras listas de cursos, la plataforma es una parte importante de la descripción del recurso. Esto se debe a que las plataformas de cursos tienen diferentes prestaciones y modelos de acceso. Si bien generalmente no incluimos un libro que requiere de registro previo, muchas plataformas de cursos tienen la casualidad de no funcionar sin algún tipo de cuenta. Un ejemplo de plataformas de cursos podrían ser: Coursera, EdX, Udacity y Udemy. Cuando un curso depende de una plataforma, el nombre de dicha plataforma debe aparecer entre paréntesis.
-- YouTube. Tenemos muchos cursos que consisten en listas de reproducción de YouTube. No incluimos Youtube como plataforma, sino que tratamos de incluir al creador de Youtube, el cuál es a menudo una sub-plataforma en sí.

 - Vídeos de YouTube. Por lo general, no vinculamos a vídeos individuales de YouTube a menos que tengan más de una hora de duración y estén estructurados como un curso o un tutorial.
-- LeanPub. LeanPub aloja libros con una amplia variedad de modelos de acceso. A veces, un libro se puede leer sin registrarse; en otras, un libro requiere una cuenta LeanPub para tener acceso gratuito. Dada la calidad de los libros y la mezcla y fluidez de los modelos de acceso Leanpub, damos validez a estos últimos anexando la nota de acceso: `*(cuenta Leanpub o email válido requerido)*`.

 - Es posible especificar más de un fichero a comprobar. Simplemente use un espacio para separar cada entrada.
-- Si especifica más de un archivo, los resultados obtenidos se basan en el estado del último archivo verificado. Debe tenerlo en cuenta ya que, debido a esto, puede obtener falsos positivos al finalizar el proceso.

     * *دوره‌ها* : دوره محتوایی آموزشی است که کتاب نیست. مثلا [این یک دوره است](http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-006-introduction-to-algorithms-fall-2011/).
-    * *آموزش‌های تعاملی* : وبسایتی تعاملی که به کاربر اجازه‌ی تایپ کد یا دستور می‌دهد و نتیجه را ارزیابی می‌کند (منظور ما از "ارزیابی"، "نمره‌دهی" نیست). مثلا: [Try Haskell](http://tryhaskell.org), [Try Github](http://try.github.io).

 ### فرمت‌بندی
 
 * همه فهرست‌ها فایل‌های ".md" هستند. سعی کنید دستور زبان [Markdown](https://guides.github.com/features/mastering-markdown/) را یاد بگیرید. ساده است!
 * همه فهرست‌ها با یک فهرست محتوایی شروع می‌شود. ایده این است که همه بخش‌ها و زیربخش‌ها در این فهرست محتوایی لیست و لینک شوند. این فهرست محتوایی را به ترتیب الفبایی قرار دهید.
 * بخش‌ها از تیترهای سطح 3 (`###`) استفاده می‌کنند و زیربخش‌ها از تیترهای سطح 4 (`###`).
+
 ایده این است که این موارد رعایت شوند:
+
 * `2` خط خالی بین آخرین لینک و بخش جدید
 * `1` خط خالی بین تیتر و لینک اول همان بخش
 * `0` خط خالی بین دو لینک
 * `1` خط خالی در آخر هر فایل `.md`
+

 - siguraduhin na ang isang libro ay libre. I-double check kung kinakailangan. Nakakatulong ito sa mga admin kung magkomento ka sa PR kung bakit sa tingin mo ay libre ang libro.
 - hindi kami tumatanggap ng mga file na naka-host sa Google Drive, Dropbox, Mega, Scribd, Issuu at iba pang katulad na mga platform sa pag-upload ng file

 ### Mga Tala
 
 Bagama't medyo simple ang mga pangunahing kaalaman, mayroong malaking pagkakaiba-iba sa mga mapagkukunang inilista namin. Narito ang ilang tala sa kung paano natin haharapin ang pagkakaiba-iba na ito.
 
+
 #### Metadata
 
 Nagbibigay ang aming mga listahan ng kaunting hanay ng metadata: mga pamagat, URL, tagalikha, platform, at tala sa pag-access.
 
+
 ##### Mga pamagat
 
 - Walang naimbentong pamagat. Sinusubukan naming kumuha ng mga pamagat mula sa mga mapagkukunan mismo; ang mga nag-aambag ay pinapayuhan na huwag mag-imbento ng mga pamagat o gamitin ang mga ito sa editoryal kung ito ay maiiwasan. Ang isang pagbubukod ay para sa mas lumang mga gawa; kung pangunahin ang mga ito sa makasaysayang interes, ang isang taon sa panaklong na nakadugtong sa pamagat ay tumutulong sa mga user na malaman kung sila ay interesado.
 - Walang pamagat ng ALLCAPS. Kadalasan ay angkop ang title case, ngunit kapag may pagdududa, gamitin ang capitalization mula sa source
 
+
 ##### URLs
 
 - Hindi namin pinahihintulutan ang mga pinaikling URL.
 - Dapat alisin ang mga tracking code sa URL.
 - Dapat na i-escape ang mga internasyonal na URL. Karaniwang nire-render ito ng mga browser bar sa Unicode, ngunit gumamit ng kopya at i-paste.
-- Ang mga Secure (https) na URL ay palaging mas gusto kaysa sa mga hindi secure na (http) na mga url kung saan ipinatupad ang https.
+- Ang mga Secure (`https`) na URL ay palaging mas gusto kaysa sa mga hindi secure na (`http`) na mga url kung saan ipinatupad ang HTTPS.
 - Hindi namin gusto ang mga URL na tumuturo sa mga webpage na hindi nagho-host ng nakalistang mapagkukunan, ngunit sa halip ay tumuturo sa ibang lugar.
 
+
 ##### Mga tagalikha
 
 - Gusto naming pasalamatan ang mga lumikha ng mga libreng mapagkukunan kung saan naaangkop, kabilang ang mga tagasalin!
 - Para sa mga isinaling gawa ang orihinal na may-akda ay dapat na kredito.
 - Hindi namin pinahihintulutan ang mga link para sa Mga Tagalikha.
-- Para sa compilation o remixed na mga gawa, maaaring kailanganin ng "creator" ang isang paglalarawan. Halimbawa, ang mga aklat na "GoalKicker" o "RIP Tutorial" ay kinikilala bilang "`Compiled from StackOverflow Documentation`"
+- Para sa compilation o remixed na mga gawa, maaaring kailanganin ng "creator" ang isang paglalarawan. Halimbawa, ang mga aklat na "GoalKicker" o "RIP Tutorial" ay kinikilala bilang "`Compiled from StackOverflow Documentation`".
+
 
 ##### Mga Platform at Mga Tala sa Pag-access
 
 - Kurso. Lalo na para sa aming mga listahan ng kurso, ang platform ay isang mahalagang bahagi ng paglalarawan ng mapagkukunan. Ito ay dahil ang mga platform ng kurso ay may iba't ibang mga affordance at mga modelo ng pag-access. Bagama't karaniwang hindi namin ilista ang isang aklat na nangangailangan ng pagpaparehistro, maraming mga platform ng kurso ang may mga affordance na hindi gumagana nang walang isang uri ng account. Kasama sa mga halimbawang platform ng kurso ang Coursera, EdX, Udacity, at Udemy. Kapag ang isang kurso ay nakasalalay sa isang platform, ang pangalan ng platform ay dapat na nakalista sa mga panaklong.
-- YouTube. Marami kaming mga kurso na binubuo ng mga playlist sa YouTube. Hindi namin inilista ang Youtube bilang isang platform, sinusubukan naming ilista ang tagalikha ng Youtube, na kadalasan ay isang sub-platform.
+- YouTube. Marami kaming mga kurso na binubuo ng mga playlist sa YouTube. Hindi namin inilista ang YouTube bilang isang platform, sinusubukan naming ilista ang tagalikha ng YouTube, na kadalasan ay isang sub-platform.
 - Mga video ng YouTube. Karaniwang hindi kami nagli-link sa mga indibidwal na video sa YouTube maliban kung ang mga ito ay higit sa isang oras ang haba at nakabalangkas tulad ng isang kurso o isang tutorial.
-- Leanpub. Nagho-host ang Leanpub ng mga aklat na may iba't ibang modelo ng access. Minsan ang isang libro ay maaaring basahin nang walang pagpaparehistro; minsan ang isang libro ay nangangailangan ng isang Leanpub account para sa libreng pag-access. Dahil sa kalidad ng mga aklat at ang pinaghalong mga modelo ng pag-access sa Leanpub, pinahihintulutan namin ang paglilista ng huli kasama ang tala sa pag-access `*(Leanpub account o valid na email ang hinihiling)*`

+
 
 #### Mga genre
 
 Ang unang tuntunin sa pagpapasya kung saang listahan kabilang ang isang mapagkukunan ay upang makita kung paano inilalarawan ng mapagkukunan ang sarili nito. Kung ito ay tinatawag na isang libro, marahil ito ay isang libro.

 ### Remarques
 
 Bien que les bases soient relativement simples, il existe une grande diversité dans les ressources que nous répertorions. Voici quelques notes sur la façon dont nous gérons cette diversité.
 
+
 #### Métadonnées
 
 Nos listes fournissent un ensemble minimal de métadonnées : titres, URL, créateurs, plateformes et notes d'accès.
 
+
 ##### Titres
 
 - Pas de titres inventés. Nous essayons de prendre les titres des ressources elles-mêmes ; les contributeurs sont avertis de ne pas inventer de titres ou de ne pas les utiliser éditorialement si cela peut être évité. Une exception est pour les œuvres plus anciennes; s'ils présentent principalement un intérêt historique, une année entre parenthèses ajoutée au titre aide les utilisateurs à savoir s'ils présentent un intérêt.
 - Pas de titres TOUTES EN MAJUSCULES. Habituellement, la casse du titre est appropriée, mais en cas de doute, utilisez la majuscule de la source
 
+
 ##### URLs
 
 - Nous n'autorisons pas les URL raccourcies.
 - Les codes de suivi doivent être supprimés de l'URL.
 - Les URL internationales doivent être échappées. Les barres du navigateur les rendent généralement en Unicode, mais utilisez le copier-coller, s'il vous plaît.
-- Les URL sécurisées (https) sont toujours préférées aux URL non sécurisées (http) où https a été implémenté.
+- Les URL sécurisées (`https`) sont toujours préférées aux URL non sécurisées (`http`) où HTTPS a été implémenté.
 - Nous n'aimons pas les URL qui pointent vers des pages Web qui n'hébergent pas la ressource répertoriée, mais pointent plutôt ailleurs.
 
+
 ##### Créateurs
 
 - Nous voulons créditer les créateurs de ressources gratuites le cas échéant, y compris les traducteurs !
 - Pour les œuvres traduites, l'auteur original doit être crédité.
 - Nous n'autorisons pas les liens pour les créateurs.
-- Pour les compilations ou les travaux remixés, le "créateur" peut avoir besoin d'une description. Par exemple, les livres "GoalKicker" sont crédités comme "Compilé à partir de la documentation StackOverflow"
+- Pour les compilations ou les travaux remixés, le "créateur" peut avoir besoin d'une description. Par exemple, les livres "GoalKicker" sont crédités comme "`Compilé à partir de la documentation StackOverflow`" (en anglais: `Compiled from StackOverflow documentation`).
+
 
 ##### Plateformes et notes d'accès
 
 - Cours. Surtout pour nos listes de cours, la plateforme est une partie importante de la description de la ressource. En effet, les plates-formes de cours ont des options et des modèles d'accès différents. Bien que nous ne répertoriions généralement pas un livre nécessitant une inscription, de nombreuses plateformes de cours ont des options qui ne fonctionnent pas sans une sorte de compte. Des exemples de plates-formes de cours incluent Coursera, EdX, Udacity et Udemy. Lorsqu'un cours dépend d'une plateforme, le nom de la plate-forme doit être indiqué entre parenthèses.
-- Youtube. Nous avons de nombreux cours qui se composent de listes de lecture YouTube. Nous ne répertorions pas Youtube comme plateforme, nous essayons de répertorier le créateur Youtube, qui est souvent une sous-plateforme.
-- Vidéos youtube. Nous ne créons généralement pas de liens vers des vidéos YouTube individuelles, sauf si elles durent plus d'une heure et sont structurées comme un cours ou un didacticiel.
-- Leanpub. Leanpub héberge des livres avec une variété de modèles d'accès. Parfois, un livre peut être lu sans inscription ; parfois un livre nécessite un compte Leanpub pour un accès gratuit. Compte tenu de la qualité des livres et du mélange et de la fluidité des modèles d'accès Leanpub, nous autorisons l'inscription de ces derniers avec la note d'accès *(compte Leanpub ou email valide demandé)*

 ### Pedoman
+
 - Pastikan sebuah buku benar-benar gratis. Periksa kembali jika perlu. Ini membantu administrator jika Anda menjelaskan dalam PR Anda mengapa menurut Anda buku tersebut gratis.
-- Kami tidak merekam file yang ada di Google Drive, Dropbox, Mega, Scribd, Issuu atau platform unggahan yang sebanding.
-- Masukkan tautan dalam urutan abjad. Jika Anda menemukan tautan yang salah dimasukkan, harap perbaiki pesanan dan buka PR.

 - Tautan `https` harus selalu lebih disukai daripada tautan `http` - selama tautan tersebut mengarah ke domain dan konten yang sama.
-- Garis miring harus dihapus pada domain root: `http://example.com` alih-alih `http://example.com/ `
-- Selalu pilih tautan terpendek: `http://example.com/dir/` lebih baik daripada `http://example.com/dir/index.html`
-    + jangan gunakan penyingkat url
-- Pilih tautan ke versi terbaru alih-alih menautkan ke versi tertentu: `http://example.com/dir/book/current/` lebih baik daripada `http://example.com/dir/book/v1.0.0/index.html`

 - Jika tautan menggunakan sertifikat yang kedaluwarsa atau ditandatangani sendiri atau memiliki masalah SSL lain:
-  1. *ganti* dengan mitra `http` jika memungkinkan (karena mungkin sulit untuk mengizinkan pengecualian pada perangkat seluler).
-  2. *biarkan apa adanya* jika versi `http` tidak tersedia, tetapi tautan dapat diakses melalui` https` dengan mengabaikan peringatan di browser atau menambahkan pengecualian.

+- lebih suka komit atom (satu komit dengan penambahan/penghapusan/modifikasi) daripada komit yang lebih besar. Tidak perlu menekan komitmen Anda sebelum mengirimkan PR. (Kami tidak akan pernah menegakkan aturan ini karena ini hanya masalah kenyamanan bagi pengelola).
+- jika buku lebih tua, sertakan tanggal penerbitan dengan judul.
+- sertakan nama penulis atau nama yang sesuai. Anda dapat mempersingkat daftar penulis dengan "`et al.`".
+- jika buku belum selesai, dan masih dalam pengerjaan, tambahkan notasi "`dalam proses`", seperti yang dijelaskan [di bawah ini](#in_process).

+<!----><a id="formatting"></a>
+### Pemformatan
+
+- Semua daftar adalah file `.md`. Coba pelajari sintaks [Markdown](https://guides.github.com/features/mastering-markdown/). Itu mudah!
+- Semua daftar dimulai dengan Indeks. Idenya adalah untuk membuat daftar dan menautkan semua bagian dan subbagian di sana. Simpan dalam urutan abjad.
+- Bagian menggunakan heading level 3 (`###`), dan subbagian menggunakan heading level 4 (`####`).
+
+Idenya adalah untuk memiliki:
+
+- `2` baris kosong antara tautan terakhir dan bagian baru.
+- `1` baris kosong antara heading & tautan pertama dari bagiannya.
+- `0` baris kosong di antara dua tautan.
+- `1` baris kosong di akhir setiap file `.md`.
+
+Contoh:
+
+```text
+[...]
+* [Contoh Buku](http://example.com/example.html)
+                            (baris kosong)
+                            (baris kosong)
+### Contoh
+                            (baris kosong)
+* [Contoh Buku Lainnya](http://example.com/book.html)
+* [Beberapa Buku Lain](http://example.com/other.html)
+```
+
+- Jangan gunakan spasi diantara `]` dan `(`:
+
+    ```text
+    BURUK : * [Contoh Buku Lainnya] (http://example.com/book.html)
+    BAIK  : * [Contoh Buku Lainnya](http://example.com/book.html)
+    ```
+
+- Jika Anda menyertakan penulis, gunakan ` - ` (tanda hubung yang dikelilingi oleh satu spasi):
+
+    ```text
+    BURUK : * [Contoh Buku Lainnya](http://example.com/book.html)- John Doe
+    BAIK  : * [Contoh Buku Lainnya](http://example.com/book.html) - John Doe
+    ```
+
+- Letakkan satu spasi di antara tautan dan formatnya:
+
+    ```text
+    BURUK : * [Buku yang Sangat Bagus](https://example.org/book.pdf)(PDF)
+    BAIK  : * [Buku yang Sangat Bagus](https://example.org/book.pdf) (PDF)
+    ```
+
+- Penulis diletakan sebelum format file:
+
+    ```text
+    BURUK : * [Buku yang Sangat Bagus](https://example.org/book.pdf)- (PDF) Jane Roe
+    BAIK  : * [Buku yang Sangat Bagus](https://example.org/book.pdf) - Jane Roe (PDF)
+    ```
+
+- Format lebih dari satu:
+
+    ```text
+    BURUK : * [Contoh Buku Lainnya](http://example.com/)- John Doe (HTML)
+    BURUK : * [Contoh Buku Lainnya](https://downloads.example.org/book.html)- John Doe (situs download)
+    BAIK  : * [Contoh Buku Lainnya](http://example.com/) - John Doe (HTML) [(PDF, EPUB)](https://downloads.example.org/book.html)
+    ```
+
+- Cantumkan tahun penerbitan dalam judul buku lama:
+
+    ```text
+    BURUK : * [Buku yang Sangat Bagus](https://example.org/book.html) - Jane Roe - 1970
+    BAIK  : * [Buku yang Sangat Bagus (1970)](https://example.org/book.html) - Jane Roe
+    ```

+### Catatan
+
+Meskipun dasar-dasarnya relatif sederhana, ada keragaman besar dalam sumber daya yang kami daftarkan. Berikut adalah beberapa catatan tentang bagaimana kita menghadapi keragaman ini.
+
+
+#### Metadata
+
+Daftar kami menyediakan kumpulan metadata minimal: judul, URL, pembuat, platform, dan catatan akses.
+
+
+<!----><a id="titles"></a>
+##### Judul
+
+- Tidak ada judul yang diciptakan. Kami mencoba mengambil judul dari sumber itu sendiri; kontributor diperingatkan untuk tidak membuat judul atau menggunakannya secara editorial jika hal ini dapat dihindari. Pengecualian adalah untuk karya yang lebih tua; jika mereka terutama memiliki minat historis, satu tahun dalam tanda kurung yang ditambahkan ke judul membantu pengguna mengetahui apakah mereka menarik.
+- Tidak ada judul SEMUANYA KAPITAL. Biasanya judul kasus sesuai, tetapi jika ragu gunakan kapitalisasi dari sumbernya.
+
+
+##### URLs
+
+- Kami tidak mengizinkan URL yang dipersingkat.
+- Kode pelacakan harus dihapus dari URL.
+- URL internasional harus diloloskan. Bilah peramban biasanya merender ini ke Unicode, tetapi gunakan salin dan tempel.
+- URL aman (`https`) selalu lebih disukai daripada url tidak aman (`http`) di mana HTTPS telah diterapkan.
+- Kami tidak menyukai URL yang mengarah ke halaman web yang tidak menghosting sumber daya yang terdaftar, melainkan menunjuk ke tempat lain.
+
+
+<!----><a id="creators"></a>
+##### Pencipta
+
+- Kami ingin menghargai pencipta sumber daya gratis jika perlu, termasuk penerjemah!
+- Untuk karya terjemahan penulis asli harus dikreditkan.
+- Kami tidak mengizinkan tautan untuk Kreator.
+- Untuk karya kompilasi atau remix, "pencipta" mungkin memerlukan deskripsi. Misalnya, buku "GoalKicker" dikreditkan sebagai "`Dikompilasi dari dokumentasi StackOverflow`" (dalam Bahasa Inggris: `Compiled from StackOverflow documentation`).
+
+
+<!----><a id="platforms-and-access-notes"></a>
+##### Platform dan Catatan Akses
+
+- Kursus. Khusus untuk daftar kursus kami, platform merupakan bagian penting dari deskripsi sumber daya. Ini karena platform kursus memiliki keterjangkauan dan model akses yang berbeda. Meskipun kami biasanya tidak akan mencantumkan buku yang memerlukan pendaftaran, banyak platform kursus memiliki keterjangkauan yang tidak berfungsi tanpa semacam akun. Contoh platform kursus termasuk Coursera, EdX, Udacity , dan Udemy. Jika kursus bergantung pada platform, nama platform harus dicantumkan dalam tanda kurung.
+- YouTube. Kami memiliki banyak kursus yang terdiri dari daftar putar YouTube. Kami tidak mencantumkan YouTube sebagai platform, kami mencoba mencantumkan pembuat YouTube, yang seringkali merupakan sub-platform.
+- Video YouTube. Kami biasanya tidak menautkan ke video YouTube individu kecuali jika durasinya lebih dari satu jam dan terstruktur seperti kursus atau tutorial.
+- Leanpub. Leanpub menyelenggarakan buku dengan berbagai model akses. Terkadang sebuah buku dapat dibaca tanpa registrasi; terkadang sebuah buku memerlukan akun Leanpub untuk akses gratis. Mengingat kualitas buku dan campuran dan fluiditas model akses Leanpub, kami mengizinkan daftar yang terakhir dengan catatan akses `*(Akun Leanpub atau email yang valid diminta)*`.
+
+
+<!----><a id="genres"></a>
+#### Genre
+
+Aturan pertama dalam memutuskan daftar mana yang termasuk dalam sumber daya adalah melihat bagaimana sumber daya itu menggambarkan dirinya sendiri. Jika itu menyebut dirinya sebuah buku, maka mungkin itu adalah sebuah buku.
+
+
+<!----><a id="genres-we-dont-list"></a>
+##### Genre yang tidak kami cantumkan
+
+Karena Internet sangat luas, kami tidak memasukkan dalam daftar kami:
+
+- blog
+- postingan blog
+- artikel
+- situs web (kecuali yang menghosting BANYAK item yang kami daftarkan).
+- video yang bukan kursus atau screencasts.
+- bab buku
+- sampel penggoda dari buku
+- Saluran IRC atau Telegram
+- Celana panjang atau milis
+
+Daftar pemrograman kompetitif kami tidak seketat pengecualian ini. Lingkup repo ditentukan oleh komunitas; jika Anda ingin menyarankan perubahan atau penambahan ruang lingkup, silakan gunakan masalah untuk membuat saran.
+
+
+<!----><a id="books-vs-other-stuff"></a>
+##### Buku vs. Barang Lainnya
+
+Kami tidak rewel tentang kebukuan. Berikut adalah beberapa atribut yang menandakan bahwa sumber daya adalah sebuah buku:
+
+- memiliki ISBN (Nomor Buku Standar Internasional)
+- memiliki Daftar Isi
+- versi yang diunduh, terutama ePub, ditawarkan
+- memiliki edisi
+- itu tidak tergantung pada konten atau video interaktif
+- mencoba untuk mencakup topik secara komprehensif
+- itu mandiri
+
+Ada banyak buku yang kami daftarkan yang tidak memiliki atribut ini; itu bisa tergantung pada konteksnya.
+
+
+<!----><a id="books-vs-courses"></a>
+##### Buku vs. Kursus
+
+Terkadang ini sulit untuk dibedakan!
+
+Kursus sering kali memiliki buku teks terkait, yang akan kami daftarkan dalam daftar buku kami. Kursus memiliki kuliah, latihan, tes, catatan atau alat bantu didaktik lainnya. Sebuah kuliah atau video dengan sendirinya bukanlah sebuah kursus. Sebuah powerpoint bukanlah kursus.
+
+
+<!----><a id="interactive-tutorials-vs-other-stuff"></a>
+##### Tutorial Interaktif vs. Hal-hal lain
+
+Jika Anda dapat mencetaknya dan mempertahankan esensinya, itu bukan Tutorial Interaktif.
+
+
+<!----><a id="automation"></a>
+### Otomatisasi
+
+- Pemformatan penegakan aturan otomatis melalui [GitHub Actions](https://github.com/features/actions) gunakan [fpb-lint](https://github.com/vhf/free-programming-books-lint) (lihat [`.github/workflows/fpb-lint.yml`](../.github/workflows/fpb-lint.yml)).
+- Validasi URL menggunakan [awesome_bot](https://github.com/dkhamsing/awesome_bot).
+- Untuk memicu validasi URL, *push commit* yang menyertakan pesan komit yang berisi `check_urls=file_to_check`:
+
+    ```properties
+    check_urls=free-programming-books.md free-programming-books-id.md
+    ```
+
+- Anda dapat menentukan lebih dari satu file untuk diperiksa, menggunakan satu spasi untuk memisahkan setiap entri.
+- Jika Anda menentukan lebih dari satu file, hasil build didasarkan pada hasil file terakhir yang diperiksa. Anda harus menyadari bahwa Anda dapat melewati build hijau karena hal ini, jadi pastikan untuk memeriksa log build di akhir Pull Request dengan mengklik "Show all checks" -> "Details".

 ### Note
 
 Mentre le basi sono relativamente semplici, c'è una notevole differenza tra le risorse che inseriamo nelle liste. Qui ci sono alcuni appunti su come affrontiamo queste diversità.
 
+
 #### Metadata
 
 I nostri elenchi forniscono un set minimo di metadati: titoli, URLs, autori, piattaforme e note di accesso.
 
+
 ##### Titoli
 
 - Non inventiamo i titoli. Cerchiamo di prendere i titoli dalla risorsa originale; i contributori sono invitati a non inventare titoli o usarli editorialmente se questo può essere evitato. Un'eccezione è per i libri più vecchi; se sono principalmente di interesse storico, l'anno tra parentesi inserito nel titolo aiuta gli utenti a capire se sono interessati a quella risorsa.
 - Niente titoli completamente in MAIUSCOLO. Di solito il title case è appropriato, ma in caso di dubbio usa le maiuscole utilizzate nella fonte.
 
+
 ##### URLs
 
 - Non per mettiamo di rimpicciolire il link con gli appositi strumenti.
 - Il codice di tracciamento deve essere rimosso dall'URL.
 - Gli URL internazionali devono essere evitati. Le barre del browser in genere li rendono in Unicode, ma usa copia e incolla, per favore.
-- I link sicuri (https) sono preferibili al posto dei link non sicuri (http), dove l'https è stato implementato.
+- I link sicuri (`https`) sono preferibili al posto dei link non sicuri (`http`), dove l'HTTPS è stato implementato.
 - Non ci piacciono gli URL che reindirizzano in una pagina che non hosta la risorsa, ma invece reindirizza altrove.
 
+
 ##### Autori
 
 - Vogliamo dare i crediti agli autori ove appropriato, anche ai traduttori!
 - Per i lavori tradotti, l'autore originale dovrebbe essere incluso.
 - Non permettiamo collegamenti per gli autori.
-- Per le compilation o remix, il "creatore" potrebbe aver bisogno di una descrizione. Ad esempio, i libri "GoalKicker" o "RIP Tutorial" sono accreditati come "Compiled from StackOverflow documentation"
+- Per le compilation o remix, il "creatore" potrebbe aver bisogno di una descrizione. Ad esempio, i libri "GoalKicker" o "RIP Tutorial" sono accreditati come "`Compiled from StackOverflow documentation`".
+
 
 ##### Piattaforme e note di accesso
 
 - Corsi. Specialmente per la nostra liste dei corsi, la piattaforma è una parte importante della descrizione. Questo perché le varie piattaforme di corsi hanno diverse affordance e metodi di accesso. Mentre solitamente i libri non hanno bisogno di un account per essere letti, molte piattaforme di corsi ne hanno bisogno. Esempi di piattaforme di corsi sono Coursera, EdX, Udacity e Udemy. Quando un corso dipende dalla piattaforma, il suo nome dovrebbe essere incluso tra parentesi.
 - YouTube. Abbiamo molti corsi che consistono in playlist di YouTube. Non consideriamo YouTube come piattaforma, cerchiamo di inserire il creatore del corso, che è spesso una sotto-piattaforma.
 - Video YouTube. Solitamente non accettiamo singoli video YouTube, a meno che non siano più lunghi di un'ora e che siano strutturati come un corso o un tutorial.
-- Leanpub. Leanpub ospita libri con varie modalità di accesso. Alcune volte i libri possono essere letti senza l'obbligo di registrazione; alcune volte è necessario creare un account gratuito su Leanpub. Data la qualità dei libri e la commistione e fluidità dei modelli di accesso Leanpub, consentiamo di elencare questi ultimi con la nota di accesso *(Leanpub account or valid email requested)*

 #### Generi
 
 La prima regola è decidere a quale lista appartiene di più una risorsa. Se si definisce un libro, allora forse è un libro.

 ### Automazione
 
-- L'applicazione delle regole di formattazione è automatizzata tramite [GitHub Actions](https://github.com/features/actions) usando [fpb-lint](https://github.com/vhf/free-programming-books-lint) (guarda [.github/workflows/fpb-lint.yml](.github/workflows/fpb-lint.yml))

 - La validazione dell'URL usa [awesome_bot](https://github.com/dkhamsing/awesome_bot)
 - Per attivare la convalida dell'URL, invia un commit che includa un messaggio di commit contenente `check_urls=file_to_check`:

 - È possibile specificare più di un file da controllare, utilizzando un singolo spazio per separare ogni voce.
-- Se specifichi più di un file, i risultati della build si basano sul risultato dell'ultimo file controllato. Dovresti essere consapevole che potresti ottenere il passaggio di build verdi a causa di ciò, quindi assicurati di ispezionare il registro di build alla fine della richiesta pull facendo clic su "Show all checks" -> "Details".

 ### 노트(쪽지)
 
 각 파일의 형식은 간단하지만, 목록에는 다양한 형태와 종류의 자료들이 존재할 수 있습니다. 아래에 나열될 항목들은 저희가 그런 다양성을 어떻게 다르는지에 대한 설명 입니다.
 
+
 #### 메타데이터
 
 각 목록은 최소한의 메타데이터만을 제공합니다: 제목, 바로가기 주소, 제작자, 플랫폼, 그리고 접속 노트
 
+
 ##### 제목
 
 - 원제를 사용하세요. 저희는 원작(원본)의 제목을 사용하기를 원합니다. 기여자들은 가능한 원제에 가깝거나 동일한 제목을 제공하여야 합니다. 예외는 오래된 책들입니다. 독자들의 더 쉬운 이해와 검색을 위해 현대의 언어로 제목을 새로 짓는것은 허가됩니다.
 - 대문자로만 이루어진 제목은 금지됩니다. 대부분 경우에 title case가 허가되지만, 확실하지 않다면 자료에 명시된 방식으로 기술 하세요.
 
+
 ##### 바로가기 주소
 
 - 주소 길이를 줄이는 행위는 허가되지 않습니다.
 - 추적을 위한 코드는 주소에서 제거되어야 합니다.
 - 주소에 영어가 아닌 언어가 포함 된 주소는 허가되지 않습니다. 대부분의 브라우져에서 정상적인 동작을 하지만, 주소창을 그대로 복사해주세요. 부탁드립니다.
-- 보안 주소(https)가 존재하는 경우, 보안 주소가 일반 주소(http)보다 선호됩니다.
+- 보안 주소(`https`)가 존재하는 경우, 보안 주소가 일반 주소(`http`)보다 선호됩니다.
 - 설명과 다른 웹페이지로 향하는 바로가기 주소는 선호되지 않습니다.
 
+
 ##### 제작자
 
 - 저희는 무료로 자료들을 배포하는 제작자들(번역가들 포함)에게 감사함을 표합니다!
 - 번역된 자료들의 경우, 원작자들이 우선적으로 명시되어야 합니다.
 - 제작자들의 정보로 향하는 바로가기 주소는 허가되지 않습니다.
-- 여러 작업물이 조합된 자료의 경우, "제작자"는 설명이 필요할 수 있습니다. 예를 들어, "GoalKicker" 책들의 제작자들은 "Compiled from StackOverflow documentation"로 명시되어야 합니다.

+
 
 ##### 플랫폼과 접속 노트
 
 - 강좌, 특히 걍좌 목록의 경우, 플랫폼을 명시하는것이 필수적입니다. 각각의 강좌들의 플랫폼을 추가하여야 무료로 접속할 수 있음을 이용자들이 인지 할 수 있습니다. 일반적으로 로그인이 필요한 책은 목록에 포함하지 않지만, 강좌는 대부분 계정을 생성하지 않으면 접근 할 수 없기 때문에 예외로 합니다. 예시로는 Coursera, EdX, Udacity, 그리고 Udemy가 있습니다. 해당 강좌들이 플랫폼 의존적이라면, 플랫폼의 이름은 반드시 포함되어야 합니다.
-- 만약 강좌가 유튜브에 존재하는 경우, 유튜브는 플랫폼으로 간주하지 않고, 크리에이터를 명시합니다.
-- 유튜브 영상들은 각각의 영상이 한시간이 넘지 않는 경우에는 바로가기 주소를 포함하지 않습니다.
-- Leanpub는 많은 책들과 강좌에 접근을 제공합니다. 경우에 따라 회원가입 없이 접근 할 수 있는 책들 또한 존재합니다. 경우에 따라 *(Leanpub account or valid email requested)* 노트를 포함하여 목록을 작성해야 합니다.
+- 유튜브. YouTube 재생 목록으로 구성된 많은 과정이 있습니다. YouTube를 플랫폼으로 나열하지 않고 종종 하위 플랫폼인 YouTube 제작자를 나열하려고 합니다.
+- 유튜브 동영상. 우리는 일반적으로 1시간 이상 길이가 코스나 튜토리얼처럼 구성되지 않는 한 개별 YouTube 동영상에 링크하지 않습니다.
+- Leanpub는 많은 책들과 강좌에 접근을 제공합니다. 경우에 따라 회원가입 없이 접근 할 수 있는 책들 또한 존재합니다. 경우에 따라 `*(Leanpub account or valid email requested)*` 노트를 포함하여 목록을 작성해야 합니다.

 - `1` linha em branco entre o título e o primeiro _link_ da seção.
 - `0` linhas em branco entre dois _links_.

 ### Observações
 
 As noções básicas são relativamente simples, mas há uma grande diversidade de materiais que listamos. Aqui estão algumas observações sobre como tratamos essa diversidade.
 
+
 #### Metadados
 
 Nossas listas fornecem um conjunto mínimo de metadados: títulos, URLs, criadores, plataformas e notas de acesso.
 
+
 ##### Títulos
 
 - Sem títulos inventados. Tentamos utilizar os títulos dos próprios materiais; contribuidores são aconselhados a não inventar títulos ou usá-los editorialmente se possível evitar. Uma exceção é para trabalhos antigos; se forem primariamente de interesse histórico, o ano entre parênteses adicionado ao título ajuda os usuários a saber se é de seu interesse.
 - Sem título EM CAIXA ALTA. Normalmente "_title case_" é apropriado. Em caso de dúvida, use a capitalização da fonte.
 
+
 ##### URLs
 
 - Não permitimos encurtadores de URLs.
 - Códigos de rastreamento devem ser removidos da URL.
 - URLs internacionais devem ser escapadas. Barras de endereço dos navegadores normalmente renderizam eles em Unicode, mas use copiar e colar, por favor.
-- URLs seguras (https) sempre são preferidas no lugar de URLs não-seguras (http) quando https estiver disponível.
+- URLs seguras (`https`) sempre são preferidas no lugar de URLs não-seguras (`http`) quando HTTPS estiver disponível.
 - Não gostamos de URLs que apontam para páginas que não hospedam o material listado, mas apontam para outro lugar.
 
+
 ##### Criadores
 
 - Queremos creditar os criadores do material gratuito apropriadamente, incluindo tradutores!
 - Para trabalhos traduzidos, o autor original deve ser creditado.
 - Não permitimos _links_ para Criadores.
-- Para compilações ou trabalhos remixados, o "criador" pode precisar de uma descrição. Por exemplo, os livros "GoalKicker" são creditados como "Compilado da documento do StackOverflow"
+- Para compilações ou trabalhos remixados, o "criador" pode precisar de uma descrição. Por exemplo, os livros "GoalKicker" são creditados como "`Compilado da documento do StackOverflow`" (em inglês: "`Compiled from StackOverflow documentation`").
+
 
 ##### Plataforma e Notas de Acesso
 
 - Cursos. Especificamente para nossa lista de cursos, a plataforma é uma parte importante da descrição do material. Isso acontece pois plataformas de cursos possuem _affordances_ e modelos de acesso diferentes. Normalmente não listamos um livro que requer um cadastro, muitas plataformas de cursos possuem _affordances_ que não funcionam sem algum tipo de conta. Exemplos de plataformas de cursos incluem Coursera, EdX, Udacity, e Udemy. Quando o curso depende da plataforma, o nome da plataforma deve ser listado em parênteses.
 - YouTube. Temos muitos cursos que consistem em _playlists_ do YouTube. Não listamos YouTube como uma plataforma, tentamos listar o criador no YouTube, que normalmente é uma subplataforma.
 - Vídeos do YouTube. Normalmente não usamos vídeos do YouTube individuais a não ser que tenham mais de uma hora e sejam estruturados como um curso ou tutorial.
-- Leanpub. Leanpub hospeda livros com uma variedade de modelos de acesso. Algumas vezes, um livro pode ser lido sem necessidade de registro; algumas vezes um livro requer uma conta Leanpub para acesso gratuito. Dada a qualidade dos livros e a mistura e fluidez dos modelos de acesso do Leanpub, permitimos a listagem deste com uma observação de acesso *(Conta Leanpub ou email válido solicitado)*

 #### Gêneros
 
 A primeira regra ao decidir a qual lista um material pertence é ver como o próprio material se descreve. Se diz que é um livro, então talvez seja um livro.
 
+
 ##### Gêneros não listados
 
 Dada a vastidão da Internet, não incluimos em nossas listas:

 - Você pode especificar mais de um arquivo para checagem, usando um espaço simples para separar cada entrada.
-- Se você especificar mais de um arquivo, os resultados de _build_ serão baseados no resultado do último arquivo verificado.

 ### Руководство
 
 - Убедитесь что книга бесплатна. При необходимости проверьте еще раз. Администраторам помогает, если вы описываете в PR, почему вы думаете, что книга бесплатная.
 - Мы не принимаем файлы, размещенные на Google Drive, Dropbox, Mega, Scribd, Issuu и других подобных платформах для загрузки файлов.
 - Вставляйте ссылки в алфавитном порядке. Если вы видите ссылку нарушающую порядок, измените ее порядок и отправьте PR
 - Используйте ссылку с наиболее авторитетным источником (то есть сайт автора лучше, чем сайт редактора, что лучше, чем сторонний сайт)
-    + не с файловых хостингов (включая (но не ограничиваясь) ссылками на Dropbox и Google Drive)

 - Обычно предпочитают ссылку на "актуальную" версию, чем на конкретную: `http://example.com/dir/book/current/` лучше, чем `http://example.com/dir/book/v1.0.0/index.html`
 - Если ссылка имеет просроченный сертификат/самоподписанный сертификат/SSL-сертификат любого другого типа:
     1. *замените её* его эквивалентом http, если это возможно (поскольку принятие исключений может быть затруднено на мобильных устройствах).

 - Если книга более старая, укажите дату публикации в названии.
-- Укажите имя автора или имена там, где это необходимо. Вы можете сократить списки авторов с помощью «и др.».

+- Все списки представляют собой файлы с расширением `.md`. Попробуйте изучить синтаксис [Markdown](https://guides.github.com/features/mastering-markdown/). Это просто!
 - Все списки начинаются с индекса. Идея состоит в том, чтобы перечислить и связать там все разделы и подразделы. Храните их в алфавитном порядке.
 - В разделах используются заголовки уровня 3 (`###`), а в подразделах используются заголовки уровня 4 (`####`).
 
 Идея состоит в том, чтобы иметь:
+
 - `2` пустые строки между последней ссылкой и новым разделом.
 - `1` пустую строку между заголовком и первой ссылкой его раздела.
 - `0` пустых ссылок между двумя ссылками.

 ### Примечания
 
 Хотя основы относительно просты, перечисленные нами ресурсы очень разнообразны. Вот несколько замечаний о том, как мы справляемся с этим разнообразием.
 
-<a name="metadata"></a>
+
+<!----><a id="metadata"></a>
 #### Метаданные
 
 Наши списки предоставляют минимальный набор метаданных: заголовки, URL-адреса, создателей, платформы и примечания к доступу.
 
-<a name="titles"></a>
+
+<!----><a id="titles"></a>
 ##### Заголовки
 
 - Никаких вымышленных названий. Мы стараемся брать названия с самих ресурсов; призываем авторов пулреквестов не придумывать заголовки и не использовать их в редакционных целях, если этого можно избежать. Исключение составляют более старые работы; если они представляют в первую очередь исторический интерес, год в скобках, добавленный к названию, помогает пользователям узнать, представляют ли они интерес.
 - Избегайте заголовков ПОЛНОСТЬЮ ЗАГЛАВНЫМИ БУКВАМИ. Обычно уместен регистр заголовка, но в случае сомнений используйте заглавные буквы из источника.
 
-<a name="urls"></a>
+
+<!----><a id="urls"></a>
 ##### URLs
 
 - Мы не разрешаем сокращенные URL-адреса.
 - Коды отслеживания должны быть удалены из URL.
 - Международные URL-адреса должны быть экранированы. Адресная панель браузера обычно отображают их в Unicode, но, пожалуйста, используйте копирование и вставку.
-- Безопасные (https) URL-адреса всегда предпочтительнее небезопасных (http) URL-адресов, в которых реализован https.
+- Безопасные (`https`) URL-адреса всегда предпочтительнее небезопасных (`http`) URL-адресов, в которых реализован HTTPS.
 - Нам не нравятся URL-адреса, которые указывают на страницы со ссылкой на другое место вместо указанного ресурса.

 ##### Creators
 
 - Хотим поблагодарить создателей бесплатных ресурсов, где это возможно, в том числе переводчиков!
 - Для переведенных работ следует указать оригинального автора.
 - Мы не разрешаем ссылки на авторов.
-- Для подборок и смешенных изданий «создателю» может потребоваться описание. Например, книги «GoalKicker» считаются «Скомпилированными из документации StackOverflow».
+- Для подборок и смешенных изданий «создателю» может потребоваться описание. Например, книги «GoalKicker» считаются «`Скомпилированными из документации StackOverflow`» ("на английском: «`Compiled from StackOverflow documentation`»).

 ##### Платформы и примечания к доступу
 
 - Курсы. Платформа является важной частью описания ресурсов, особенно для наших списков курсов. Это связано с тем, что платформы курсов имеют разные возможности и модели доступа. Хотя мы обычно не перечисляем книги, требующие регистрации, на многих платформах курсов есть возможности, которые не работают без какой-либо учетной записи. Например, как на Coursera, EdX, Udacity и Udemy. Если курс зависит от платформы, название платформы должно быть указано в скобках.
-- YouTube. У нас есть много курсов, состоящих из плейлистов YouTube. Мы не указываем Youtube как платформу, мы пытаемся указать автора на Youtube, который часто является под-платформой.
+- YouTube. У нас есть много курсов, состоящих из плейлистов YouTube. Мы не указываем YouTube как платформу, мы пытаемся указать автора на YouTube, который часто является под-платформой.
 - YouTube видео. Обычно мы не ссылаемся на отдельные видео YouTube, если они не длится более часа или не структурированы как курс или учебное пособие.
-- Leanpub. Leanpub размещает книги с различными моделями доступа. Иногда книгу можно прочитать без регистрации; иногда для бесплатного доступа к книге требуется учетная запись Leanpub. Учитывая качество книг, а также сочетание и гибкость моделей доступа к Leanpub, мы разрешаем перечисление последних с указанием доступа *(требуется учетная запись Leanpub или действующий адрес электронной почты)*

 - Вы можете указать более одного файла для проверки, используя один пробел для разделения каждой записи.
 - Если вы укажете более одного файла, результаты сборки будут основаны на результате последнего проверенного файла. Вы должны знать, что из-за этого вы можете получить проходящие зеленые сборки, поэтому обязательно проверьте журнал сборки в конце пулреквеста, нажав "Show all checks" -> "Details".

 - Tất cả các danh sách bắt đầu bằng một Chỉ mục. Ý tưởng là liệt kê và liên kết tất cả các phần và tiểu mục ở đó. Giữ nó theo thứ tự bảng chữ cái.
 - Các phần đang sử dụng tiêu đề cấp 3 (`###`) và các tiểu mục là tiêu đề cấp 4 (`####`).

 ### Ghi Chú
 
 Mặc dù những điều cơ bản tương đối đơn giản, nhưng có sự đa dạng lớn trong các nguồn mà chúng tôi liệt kê. Dưới đây là một số lưu ý về cách chúng ta phân loại những sự đa dạng này.
 
+
 #### Metadata
 
 Danh sách của chúng tôi cung cấp một metadata: tiêu đề, URL, người tạo, nền tảng và ghi chú truy cập.
 
+
 ##### Tiêu Đề
 
 - Không được phát minh ra tiêu đề. Chúng tôi cố gắng lấy các tiêu đề từ chính các nguồn tài liệu đó; những người đóng góp được khuyến cáo không phát minh ra tiêu đề hoặc chỉnh sửa chúng nếu điều này có thể tránh được. Một ngoại lệ là đối với các tác phẩm cũ hơn; nếu họ chủ yếu quan tâm đến lịch sử, thêm số năm vào trong dấu ngoặc đơn nằm trong tiêu đề sẽ giúp người dùng biết liệu họ có quan tâm hay không.
-- Không sử dụng tiêu đề viết hoa toàn bộ. Thông thường, viết hoa tiêu đề là phù hợp, nhưng khi không chắc chắn, hãy sử dụng chữ viết hoa từ nguồn.
+- Không sử dụng tiêu đề viết HOA TOÀN BỘ. Thông thường, viết hoa tiêu đề là phù hợp, nhưng khi không chắc chắn, hãy sử dụng chữ viết hoa từ nguồn.
+
 
 ##### Các Liên Kết
 
 - Chúng tôi không cho phép các liên kết rút gọn.
 - Mã theo dõi phải được xóa khỏi liên kết.
 - Liên kết quốc tế phải được thoát. Các thanh trình duyệt thường hiển thị chúng thành Unicode, nhưng vui lòng sử dụng sao chép và dán.
-- Các liên kết an toàn (https) luôn được ưu tiên hơn các liên kết không an toàn (http) nơi https đã được triển khai.
+- Các liên kết an toàn (`https`) luôn được ưu tiên hơn các liên kết không an toàn (``http`) nơi HTTPS đã được triển khai.
 - Chúng tôi không thích các liên kết trỏ đến các trang web không lưu trữ tài liệu được liệt kê, mà thay vào đó trỏ đến nơi khác.
 
+
 ##### Người Sáng Tạo
 
 - Chúng tôi muốn ghi công những người tạo ra các tài liệu miễn phí nếu thích hợp, bao gồm cả những người dịch!
 - Đối với các tác phẩm đã dịch, tác giả gốc nên được ghi công.
 - Chúng tôi không cho phép liên kết bởi Người sáng tạo.
-- Đối với các tác phẩm tổng hợp hoặc phối lại, "người sáng tạo" có thể cần mô tả. Ví dụ: sách "GoalKicker" được ghi là "Được tổng hợp từ tài liệu StackOverflow"
+- Đối với các tác phẩm tổng hợp hoặc phối lại, "người sáng tạo" có thể cần mô tả. Ví dụ: sách "GoalKicker" được ghi là "`Được tổng hợp từ tài liệu StackOverflow`" (bằng tiếng anh: "`Compiled from StackOverflow documentation`").
+
 
 ##### Nền Tảng và Ghi Chú Truy Cập
 
 - Các khóa học. Đặc biệt đối với danh sách khóa học của chúng tôi, nền tảng là một phần quan trọng của mô tả tài liệu. Điều này là do các khóa học nền tảng có khả năng chi trả và mô hình truy cập khác nhau. Mặc dù chúng tôi thường không liệt kê một cuốn sách yêu cầu đăng ký, nhưng nhiều nền tảng khóa học có khả năng không hoạt động nếu không có một số loại tài khoản. Các nền tảng khóa học ví dụ bao gồm Coursera, EdX, Udacity và Udemy. Khi một khóa học phụ thuộc vào một nền tảng, tên nền tảng phải được liệt kê trong ngoặc đơn.
-- YouTube. Chúng tôi có nhiều khóa học bao gồm các danh sách phát trên YouTube. Chúng tôi không cho rằng Youtube như một nền tảng, chúng tôi cố gắng liệt kê người sáng tạo nội dung trên YouTube, thường là một nền tảng phụ.
+- YouTube. Chúng tôi có nhiều khóa học bao gồm các danh sách phát trên YouTube. Chúng tôi không cho rằng YouTube như một nền tảng, chúng tôi cố gắng liệt kê người sáng tạo nội dung trên YouTube, thường là một nền tảng phụ.
 - Video trên YouTube. Chúng tôi thường không có các liên kết đến các video YouTube riêng lẻ trừ khi chúng dài hơn một giờ và có cấu trúc giống như một khóa học hoặc một hướng dẫn.
-- Leanpub. Leanpub lưu trữ sách với nhiều mô hình truy cập. Đôi khi một cuốn sách có thể được đọc mà không cần đăng ký; đôi khi một cuốn sách yêu cầu tài khoản Leanpub để được truy cập miễn phí. Do chất lượng của sách và sự hỗn hợp và tính linh hoạt của các mô hình truy cập Leanpub, chúng tôi cho phép liệt kê mô hình sau cùng với ghi chú truy cập *(yêu cầu tài khoản Leanpub hoặc email hợp lệ)*

+
 
 #### Thể Loại
 
 Quy tắc đầu tiên để quyết định tài liệu thuộc danh sách nào là xem tài liệu đó mô tả thế nào. Nếu nó tự gọi nó là một cuốn sách, thì có lẽ nó là một cuốn sách.

 - on root domains, strip the trailing slash: `http://example.com` instead of `http://example.com/`
 - always prefer the shortest link: `http://example.com/dir/` is better than `http://example.com/dir/index.html`
-    + no URL shortener links

 ### Formatting
+
 - All lists are `.md` files. Try to learn [Markdown](https://guides.github.com/features/mastering-markdown/) syntax. It's simple!
 - All the lists start with an Index. The idea is to list and link all sections and subsections there. Keep it in alphabetical order.
 - Sections are using level 3 headings (`###`), and subsections are level 4 headings (`####`).
 
 The idea is to have:
+
 - `2` empty lines between last link and new section.
 - `1` empty line between heading & first link of its section.
 - `0` empty line between two links.

 ### Notes
 
 While the basics are relatively simple, there is a great diversity in the resources we list. Here are some notes on how we deal with this diversity.
 
+
 #### Metadata
 
 Our lists provide a minimal set of metadata: titles, URLs, creators, platforms, and access notes.
 
+
 ##### Titles
 
 - No invented titles. We try to take titles from the resources themselves; contributors are admonished not to invent titles or use them editorially if this can be avoided. An exception is for older works; if they are primarily of historical interest, a year in parentheses appended to the title helps users know if they are of interest.
 - No ALLCAPS titles. Usually title case is appropriate, but when doubt use the capitalization from the source
 
+
 ##### URLs
 
 - We don't permit shortened URLs.
 - Tracking codes must be removed from the URL.
 - International URLs should be escaped. Browser bars typically render these to Unicode, but use copy and paste, please.
-- Secure (https) URLs are always preferred over non-secure (http) urls where https has been implemented.
+- Secure (`https`) URLs are always preferred over non-secure (`http`) urls where HTTPS has been implemented.
 - We don't like URLs that point to webpages that don't host the listed resource, but instead point elsewhere.
 
+
 ##### Creators
 
 - We want to credit the creators of free resources where appropriate, including translators!
 - For translated works the original author should be credited.
 - We do not permit links for Creators.
-- For compilation or remixed works, the "creator" may need a description. For example, "GoalKicker" or "RIP Tutorial" books are credited as "Compiled from StackOverflow documentation"
+- For compilation or remixed works, the "creator" may need a description. For example, "GoalKicker" or "RIP Tutorial" books are credited as "`Compiled from StackOverflow documentation`".
+
 
 ##### Platforms and Access Notes
 
 - Courses. Especially for our course lists, the platform is an important part of the resource description. This is because course platforms have different affordances and access models. While we usually won't list a book that requires a registration, many course platforms have affordances that don't work without some sort of account. Example course platforms include Coursera, EdX, Udacity, and Udemy. When a course depends on a platform, the platform name should be listed in parentheses.
-- YouTube. We have many courses which consist of YouTube playlists. We do not list Youtube as a platform, we try to list the Youtube creator, which is often a sub-platform.
+- YouTube. We have many courses which consist of YouTube playlists. We do not list YouTube as a platform, we try to list the YouTube creator, which is often a sub-platform.
 - YouTube videos. We usually don't link to individual YouTube videos unless they are more than an hour long and are structured like a course or a tutorial.
-- Leanpub. Leanpub hosts books with a variety of access models. Sometimes a book can be read without registration; sometimes a book requires a Leanpub account for free access. Given quality of the books and the mixture and fluidity of Leanpub access models, we permit listing of the latter with the access note *(Leanpub account or valid email requested)*

Given quality of the books and the mixture and fluidity of Leanpub access models, we permit listing of the latter with the access note `*(Leanpub account or valid email requested)*`.
+
 
 #### Genres
 
 The first rule in deciding which list a resource belongs in is to see how the resource describes itself. If it calls itself a book, then maybe it's a book.
 
+
 ##### Genres we don't list
 
 Because the Internet is vast, we don't include in our lists:

 ### Automation
 
-- Formatting rules enforcement is automated via [GitHub Actions](https://github.com/features/actions) using [fpb-lint](https://github.com/vhf/free-programming-books-lint) (see [.github/workflows/fpb-lint.yml](.github/workflows/fpb-lint.yml))

 - URL validation uses [awesome_bot](https://github.com/dkhamsing/awesome_bot)
 - To trigger URL validation, push a commit that includes a commit message containing `check_urls=file_to_check`:
 
-```
-check_urls=free-programming-books.md free-programming-books-en.md
-```
+    ```properties
+    check_urls=free-programming-books.md free-programming-books-en.md
+    ```
 
 - You may specify more than one file to check, using a single space to separate each entry.
-- If you specify more than one file, results of the build are based on the result of the last file checked. You should be aware that you may get passing green builds due to this so be sure to inspect the build log at the end of the pull request by clicking on "Show all checks" -> "Details".
