-## 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.
-
-4. Σιγουρευτείτε ότι ακολουθείτε τις [παρακάτω κατευθυντήριες γραμμές](#guidelines) και σέβεστε τη [μορφοποίηση Markdown](#formatting) των αρχείων.
-
-5. Το GitHub Actions τρέχει δοκιμές για να ελέγξει ότι οι λίστες σας είναι σε αλφαβητική σειρά και τηρούνται οι κανόνες μορφοποίησης. Να θυμάστε να ελέγχετε ότι οι αλλαγές σας περνούν τις δοκιμές.

-
-<a name="guidelines"></a>
-### Κατευθυντήριες Γραμμές
-
-- σιγουρευτείτε ότι το βιβλίο είναι δωρεάν. Επανελέγξτε αν χρειάζεται. Βοηθάει τους διαχειριστές αν σχολιάζετε στο PR τον λόγο που πιστεύετε ότι αυτό το βιβλίο είναι δωρεάν.
-- δεν δεχόμαστε αρχεία που φιλοξενούνται στα Google Drive, Dropbox, Mega, Scribd, Issuu και άλλες παρόμοιες πλατφόρμες ανεβάσματος αρχείων
-- εισάγετε τους συνδέσμους σας σε αλφαβητική σειρά. Αν βάλετε έναν σύνδεσμο σε λάθος θέση, παρακαλούμε διορθώστε το και υποβάλλετε νέο PR
-- χρησιμοποιήστε έναν σύνδεσμο με την πιο έγκυρη πηγή (που σημαίνει ότι η ιστοσελίδα του συγγραφέα είναι καλύτερη από τη σελίδα του εκδότη, η οποία είναι καλύτερη από μια τρίτη ιστοσελίδα)
-    + δεν επιτρέπονται υπηρεσίες φιλοξενίας αρχείων (αυτό περιλαμβάνει (αλλά δεν περιορίζεται στους) συνδέσμους από Dropbox και Google Drive)
-- να προτιμάτε ένα σύνδεσμο `https` από έναν `http` -- αρκεί να είναι στο ίδιο domain και να εξυπηρετούν τον ίδιο περιεχόμενο
-- στα root domains, αφαιρέστε την τελευταία κάθετο: `http://example.com` αντί για `http://example.com/`
-- να προτιμάτε πάντα τους μικρότερους συνδέσμους: `http://example.com/dir/` είναι καλύτερα από `http://example.com/dir/index.html`
-    + δεν επιτρέπονται περικομμένοι σύνδεσμοι (URL shortener)
-- να προτιμάτε συνήθως τους "τρέχοντες" συνδέσμους από τους συνδέσμους "εκδόσεων": `http://example.com/dir/book/current/` είναι καλύτερα από `http://example.com/dir/book/v1.0.0/index.html`
-- αν ένας σύνδεσμος έχει ληγμένο πιστοποιητικό/αυτοϋπογεγραμμένο πιστοποιητικό/κάποια θέμα άλλου είδους με SSL:
-    1. *αντικαταστήστε το* με το `http` αντίστοιχό του αν είναι δυνατό (επειδή το να γίνονται αποδεκτές εξαιρέσεις μπορεί να είναι περίπλοκο σε φορητές συσκευές).
-    2. *αφήστε το* αν δεν υπάρχει διαθέσιμη έκδοση για `http` αντίστοιχο αλλά ο σύνδεσμος είναι ακόμα προσβάσιμος από `https` προσθέτοντας εξαίρεση στον browser ή αγνοώντας της προειδοποίηση
-    3. *αφαιρέστε το* σε κάθε άλλη περίπτωση
-- αν ένας σύνδεσμος υπάρχει σε διαφορετικά format, προσθέστε διαφορετικό σύνδεσμο με μια σημείωση για κάθε format
-- αν κάποιο υλικό υπάρχει σε διαφορετικά μέρη στο Internet
-    + χρησιμοποιείστε τον σύνδεσμο με την πιο έγκυρη πηγή (που σημαίνει ότι η ιστοσελίδα του συγγραφέα είναι καλύτερη από τη σελίδα του εκδότη, η οποία είναι καλύτερη από μια τρίτη ιστοσελίδα)
-    + αν οδηγούν σε διαφορετικές εκδόσεις, και θεωρείτε πως αυτές οι εκδόσεις είναι αρκετά διαφορετικές ώστε να έχει αξία η διατήρησή τους, προσθέστε διαφορετικό σύνδεσμο με μια σημείωση για κάθε έκδοση (δείτε το [Issue #2353](https://github.com/EbookFoundation/free-programming-books/issues/2353) για να συνεισφέρετε στη συζήτηση για τη μορφοποίηση)
-- προτιμήστε ατομικά commits (ένα commit ανά προσθήκη/διαγραφή/τροποποίηση) αντί για μεγαλύτερα commits. Δεν υπάρχει ανάγκη να συνενώνετε τα commits πριν υποβάλλετε ένα PR. (Δεν θα επιβάλλουμε ποτέ αυτόν τον κανόνα εφ' όσον είναι απλά ζήτημα διευκόλυνσης για τους διατηρητές)
-- αν το βιβλίο είναι παλιό, περιλαμβάνετε την ημερομηνία δημοσίευσης με τον τίτλο
-- συμπεριλαμβάνετε το όνομα ή τα ονόματα του συγγραφέα όπου είναι απαραίτητο. Μπορείτε να μικρύνετε τις λίστες συγγραφέων με το "et al."
-- αν το βιβλίο δεν έχει τελειώσει, και βρίσκεται ακόμα υπό συγγραφή, προσθέστε τη σημείωση "σε εξέλιξη", όπως περιγράφεται [παρακάτω.](#in_process)
-- αν το υλικό έχει ανακτηθεί χρησιμοποιώντας το Internet's Archive Wayback Machine (ή παρόμοια), προσθέτε την ένδειξη "αρχείοθετημένο" (στα αγγλικά: "archived"), όπως περιγράφεται [παρακάτω](#archived). Οι καλύτερες εκδοχές για να χρησιμοποιήσετε είναι οι πρόσφατες και πλήρεις.
-- αν ζητείται διεύθυνση ηλεκτρονικού ταχυδρομείου ή δημιουργία λογαριασμού πριν την ενεργοποίηση της λήψης, προσθέστε κατάλληλες σημειώσεις ανάλογα με τη γλώσσα σε παρένθεση, π.χ. `(διεύθυνση email *ζητείται*, δεν είναι απαραίτητη)`
-
-
-<a name="formatting"></a>
-### Μορφοποίηση
-
-- Όλες οι λίστες είναι αρχεία `.md`. Προσπαθήστε να μάθετε τη σύνταξη του [Markdown](https://guides.github.com/features/mastering-markdown/). Είναι απλή!
-- Όλες οι λίστες ξεκινούν με τα Περιεχόμενα (Index). Η ιδέα είναι να υπάρχουν σύνδεσμοι για κάθε ενότητα και υποενότητα εκεί. Διατηρήστε την αλφαβητική σειρά.
-- Οι ενότητες χρησιμοποιούν επικεφαλίδες επιπέδου 3 (`###`), και οι υποενότητες είναι επικεφαλίδες επιπέδου 4 (`####`).
-
-Η ιδέα είναι να έχουμε:
-- `2` κενές γραμμές μεταξύ τελευταίου συνδέσμου και νέας ενότητας
-- `1` κενή γραμμή μεταξύ επικεφαλίδας & πρώτου συνδέσμου της ενότητάς του
-- `0` κενές γραμμές μεταξύ δύο συνδέσμων
-- `1` κενή γραμμή στο τέλος κάθε αρχείου `.md`.

-### 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.
-- 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!
-- Για μεταφρασμένα έργα, θα πρέπει να αναφέρεται το όνομα του αρχικού συγγραφέα.
-- 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)*`

-#### Είδη
-
-Ο πρώτος κανόνας στην απόφαση για το σε ποια λίστα ανήκει το υλικό είναι να δείτε πώς περιγράφει τον εαυτό του. Αν αυτοαποκαλείται βιβλίο, τότε ίσως είναι βιβλίο.
-
-#### Είδη που δεν παραθέτουμε
-
-Επειδή το Internet είναι μεγάλο, δεν περιέχουμε στις λίστες μας:
-
-- blogs
-- blog posts
-- άρθρα
-- ιστοσελίδες (εκτός από αυτές που φιλοξενούν ΠΟΛΛΑ από τα αντικείμενα που παραθέτουμε.)
-- βίντεο που δεν είναι μαθήματα ή screencasts.
-- κεφάλαια βιβλίων
-- δείγματα από βιβλία
-- κανάλια από το IRC ή το Telegram
-- Slacks ή λίστες mailing
-
-Οι λίστες μας ανταγωνιστικού προγραμματισμού δεν είναι το ίδιο αυστηρές με αυτούς τους αποκλεισμούς. Τα περιθώρια αυτού του αποθετηρίου αποφασίζονται από την κοινότητα· αν θέλετε να προτείνετε μια αλλαγή ή μια προσθήκη στον σκοπό, παρακαλούμε χρησιμοποιήστε ένα issue για να κάνετε μια πρόταση.
-
-
-#### Βιβλία vs. Άλλα Πράγματα
-
-Δεν είμαστε τόσο γκρινιάρηδες για την βιβλιό-τητα. Ορίστε μερικά χαρακτηριστικά που εκφράζουν ότι το υλικό είναι βιβλίο:
-
-- έχει ISBN (International Standard Book Number)
-- έχει Περιεχόμενα
-- παρέχεται μια έκδοση για κατέβασμα, ιδιαίτερα αρχεία ePub.
-- έχει διαφορετικές εκδόσεις
-- δεν εξαρταίται από διαδραστικό περιεχόμενο ή βίντεο
-- προσπαθεί να καλύψει ολοκληρωτικά ένα θέμα
-- είναι αυτοτελές
-
-Υπάρχουν πολλά βιβλία που παραθέτουμε που δεν έχουν αυτά τα χαρακτηριστικά· μπορεί να εξαρτάται από την περίπτωση.
-
-
-#### Βιβλία vs. Μαθήματα
-
-Μερικές φορές μπορεί να είναι δύσκολο να τα ξεχωρίσουμε!
-
-Τα μαθήματα έχουν συχνά σχετιζόμενα βιβλία, τα οποία πρέπει να παραθέτουμε στη λίστα μας με τα βιβλία. Τα μαθήματα έχουν διαλέξεις, ασκήσεις, τεστ, σημειώσεις και άλλα διδακτικά βοηθήματα. Μια και μοναδική διάλεξη ή βίντεο δεν είναι από μόνο του μάθημα. Ένα powerpoint δεν είναι μάθημα.
-
-
-##### Διαδραστικά Σεμνάρια vs. Άλλα Πράγματα
-
-Αν μπορείτε να το τυπώσετε και να διατηρήσετε την ουσία του, δεν είναι Διαδραστικό Σεμινάριο.

-Sa pamamagitan ng pag-aambag sumasang-ayon ka sa [LICENSE](https://github.com/EbookFoundation/free-programming-books/blob/master/LICENSE) ng repositoryong ito.
-
-## Kodigo ng Pag-uugali ng Contributor
-Sa pamamagitan ng pag-aambag sumasang-ayon kang igalang ang [Code of Conduct](https://github.com/EbookFoundation/free-programming-books/blob/master/CODE_OF_CONDUCT-fil.md) ng repositoryong ito.
-
-## Sa maikling sabi
-1. "Ang isang link para madaling mag-download ng libro" ay hindi palaging isang link sa isang *libre* na libro. Mangyaring mag-ambag lamang ng libreng nilalaman. Tiyaking libre ito. Hindi kami tumatanggap ng mga link sa mga pahina na *nangangailangan* ng gumaganang mga email address upang makakuha ng mga aklat, ngunit malugod naming tinatanggap ang mga listahan na humihiling sa kanila.
-2. Hindi mo kailangang malaman ang Git: kung nakakita ka ng isang bagay na interesado na *wala pa sa repo na ito*, mangyaring magbukas ng [Issue](https://github.com/EbookFoundation/free-programming-books/issues) kasama ang iyong mga proposisyon ng link.
-    - Kung alam mo ang Git, mangyaring Fork ang repo at magpadala ng mga Pull Request (PR).
-3. Mayroon kaming 5 uri ng mga listahan. Piliin ang tama:
-
-    - *Mga libro* : PDF, HTML, ePub, isang site na nakabatay sa gitbook.io, a Git repo, etc.
-    - *Kurso* : Ang kurso ay isang materyal sa pag-aaral na hindi isang libro. [This is a course](http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-006-introduction-to-algorithms-fall-2011/).
-    - *Mga Interactive na Tutorial* : Isang interactive na website na nagbibigay-daan sa user na mag-type ng code o command at suriin ang resulta (sa pamamagitan ng "suriin" hindi namin ibig sabihin ay "grado"). e.g.: [Try Haskell](http://tryhaskell.org), [Try Github](http://try.github.io).
-    - *Mga Podcast at Screencast* : Mga podcast at screencast.
-    - *Mga Set ng Problema at Kompetisyon sa Programming* : Isang website o software na nagbibigay-daan sa iyong tasahin ang iyong mga kasanayan sa programming sa pamamagitan ng paglutas ng mga simple o kumplikadong problema, mayroon man o walang code review, mayroon man o walang paghahambing ng mga resulta sa ibang mga user.
-
-4. Siguraduhing sundin ang [guidelines below](#guidelines) at igalang ang [Markdown formatting](#formatting) ng mga file.
-
-5. Ang GitHub Actions ay magpapatakbo ng mga pagsubok upang matiyak na ang iyong mga listahan ay naka-alpabeto at sinusunod ang mga panuntunan sa pag-format. Siguraduhing suriin na ang iyong mga pagbabago ay pumasa sa mga pagsubok.

-### Mga Alituntunin
-- 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
-- ipasok ang iyong mga link sa alphabetical order. Kung makakita ka ng maling lugar na link, mangyaring muling ayusin ito at magsumite ng PR
-- gamitin ang link na may pinakamakapangyarihang pinagmulan (ibig sabihin ang website ng may-akda ay mas mahusay kaysa sa website ng editor, na mas mahusay kaysa sa isang third party na website)
-    + walang mga serbisyo sa pagho-host ng file (kabilang dito ang (ngunit hindi limitado sa) mga link ng Dropbox at Google Drive)
-- palaging mas gusto ang isang link na `https` kaysa sa isang link na `http` -- hangga't sila ay nasa parehong domain at naghahatid ng parehong nilalaman
-- sa mga root domain, tanggalin ang trailing slash: `http://example.com` sa halip na `http://example.com/`
-- palaging mas gusto ang pinakamaikling link: `http://example.com/dir/` ay mas mabuti kaysa sa `http://example.com/dir/index.html`
-    + walang URL shortener link
-- kadalasang mas gusto ang "kasalukuyang" link kaysa sa "bersyon": `http://example.com/dir/book/current/` ay mas mabuti kaysa sa `http://example.com/dir/book/v1.0.0/index.html`
-- kung ang isang link ay nag-expire na certificate/self-signed certificate/SSL isyu ng anumang iba pang uri:
-  1. *palitan ito* ng katapat nitong `http` kung maaari (dahil ang pagtanggap ng mga pagbubukod ay maaaring kumplikado sa mga mobile device).
-  2. *iwanan ito* kung walang available na bersyon ng `http` ngunit maa-access pa rin ang link sa pamamagitan ng `https` sa pamamagitan ng pagdaragdag ng exception sa browser o hindi papansinin ang babala.
-  3. *tanggalin mo* kung hindi.
-- kung mayroong isang link sa maraming format, magdagdag ng isang hiwalay na link na may tala tungkol sa bawat format
-- kung mayroong isang mapagkukunan sa iba't ibang lugar sa Internet
-    + gamitin ang link na may pinaka-makapangyarihang pinagmulan (ibig sabihin ang website ng may-akda ay mas mahusay kaysa sa website ng editor ay mas mahusay kaysa sa third party na website)
-    + kung nagli-link ang mga ito sa iba't ibang mga edisyon, at hinuhusgahan mo na ang mga edisyong ito ay sapat na naiiba upang maging sulit na panatilihin ang mga ito, magdagdag ng hiwalay na link na may tala tungkol sa bawat edisyon (see [Issue #2353](https://github.com/EbookFoundation/free-programming-books/issues/2353) upang mag-ambag sa talakayan sa pag-format.)
-- mas gusto ang atomic commit (one commit by addition/deletion/modification) higit sa mas malalaking commit. Hindi na kailangang i-squash ang iyong mga commit bago magsumite ng PR. (Hindi namin kailanman ipapatupad ang panuntunang ito dahil ito ay isang bagay lamang ng kaginhawahan para sa mga nagpapanatili)
-- kung mas luma ang aklat, isama ang petsa ng publikasyon na may pamagat.
-- isama ang pangalan ng may-akda o mga pangalan kung saan naaangkop. Maaari mong paikliin ang mga listahan ng may-akda gamit ang "`et al.`"
-- kung ang aklat ay hindi pa tapos, at ginagawa pa rin, idagdag ang "in process" notation, gaya ng inilarawan [below.](#in_process)
-- kung ang isang mapagkukunan ay naibalik gamit ang Wayback Machine ng Internet Archive (o katulad), idagdag ang "naka-archive" na notation, tulad ng inilarawan [below](#archived). Ang pinakamahusay na mga bersyon na gagamitin ay bago at kumpleto.
-- kung humiling ng email address o pag-setup ng account bago i-enable ang pag-download, magdagdag ng mga tala na naaangkop sa wika sa mga panaklong, hal.: `(email address *requested*, not required)`
-
-<a name="formatting"></a>
-### Pag-format
-- Ang lahat ng mga listahan ay `.md` files. Subukang matuto [Markdown](https://guides.github.com/features/mastering-markdown/) syntax. Simple lang!
-- Ang lahat ng mga listahan ay nagsisimula sa isang Index. Ang ideya ay ilista at i-link ang lahat ng seksyon at subsection doon. Panatilihin ito sa alpabetikong pagkakasunud-sunod.
-- Gumagamit ang mga seksyon ng antas 3 na mga heading (`###`), at ang mga subsection ay level 4 na mga heading (`####`).
-
-The idea is to have:
-- `2` walang laman na linya sa pagitan ng huling link at bagong seksyon.
-- `1` walang laman na linya sa pagitan ng heading.
-- `0` walang laman na linya sa pagitan ng dalawang link.
-- `1` walang laman na linya sa dulo ng bawat isa `.md` 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.
-- 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`"
-
-##### 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.
-- 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.
-
-##### Mga genre na hindi namin inililista
-
-Dahil malawak ang Internet, hindi namin isinasama sa aming mga listahan:
-
-- blogs
-- blog posts
-- articles
-- websites (except for those that host LOTS of items that we list.)
-- videos that aren't courses or screencasts.
-- book chapters
-- teaser samples from books
-- IRC or Telegram channels
-- Slacks or mailing lists
-
-Ang aming mga listahan ng mapagkumpitensyang programming ay hindi kasing higpit tungkol sa mga pagbubukod na ito. Ang saklaw ng repo ay tinutukoy ng komunidad; kung gusto mong magmungkahi ng pagbabago o pagdaragdag sa saklaw, mangyaring gumamit ng isyu para gawin ang mungkahi.
-
-
-##### Mga Aklat kumpara sa Iba Pang Bagay
-
-Hindi kami masyadong maselan sa mga libro. Narito ang ilang mga katangian na nagpapahiwatig na ang isang mapagkukunan ay isang libro:
-
-- mayroon itong ISBN (International Standard Book Number)
-- mayroon itong Talaan ng mga Nilalaman
-- inaalok ang isang nada-download na bersyon, lalo na ang mga ePub file.
-- ito ay may mga edisyon
-- hindi ito nakadepende sa interactive na content o mga video
-- sinusubukan nitong kumprehensibong saklawin ang isang paksa
-- ito ay may sarili
-
-Maraming mga aklat na inilista namin na walang mga katangiang ito; ito ay maaaring depende sa konteksto.
-
-
-##### Mga Aklat kumpara sa Mga Kurso
-
-Minsan ang mga ito ay maaaring mahirap makilala!
-
-Ang mga kurso ay kadalasang may kaugnay na mga aklat-aralin, na aming ililista sa aming mga listahan ng mga aklat. Ang mga kurso ay may mga lektura, pagsasanay, pagsusulit, tala o iba pang mga tulong sa didactic. Ang isang lektura o video mismo ay hindi isang kurso. Ang powerpoint ay hindi kurso.
-
-
-##### Mga Interactive na Tutorial kumpara sa Iba pang bagay
-
-Kung maaari mong i-print ito at panatilihin ang kakanyahan nito, hindi ito isang Interactive na Tutorial.

-Zelfs als je een ervaren open source-bijdrager bent, zijn er dingen die je kunnen laten struikelen. Nadat je je PR hebt ingediend, voert GitHub Actions een linter uit, waarbij vaak kleine problemen met spatiëring of alfabetisering worden gevonden. Als je een groene knop krijgt, is alles klaar voor beoordeling, maar als dat niet het geval is, klik je op "Details" onder het vinkje dat niet heeft kunnen achterhalen wat de linter niet leuk vond. Los het probleem op en voeg een commit toe aan je PR.
