+
+## 기여자 행도 강령
+이 리포지토리 기여함으로서, 모든 기여자는 이 [행동강령](https://github.com/EbookFoundation/free-programming-books/blob/master/CODE_OF_CONDUCT.md) 에 동의한 것으로 간주됩니다.
+
+## 요약
+1. "책을 쉽게 내려받을 수 있는 바로가기"는 해당 책이 무료임을 보장하지 않습니다. 이 프로젝트에 기여하기 전에 해당 바로가기가 무료임을 확인해 주십시오. 저희는 또한 작동하는 이메일을 요구하는 바로가기는 허용하지 않습니다만, 이메일을 요청하는 것들은 허용됩니다.
+2. 깃에 대해 알고 있을 필요는 없습니다: 만약 당신이 조건에 부합하면서 이미 등재되지 않은 바로가기를 발견한다면, 새로운 바로가기와 함께 새로운 [이슈](https://github.com/EbookFoundation/free-programming-books/issues)를 열 수 있습니다.
+    - 만약 깃 사용법으 알고 있다면, 해당 리포지토리를 Fork 하며 Pull request를 보내주세요.
+3. 저희는 다섯 가지의 리스트를 제공하고 있습니다. 올바른 것을 선택해 주세요:
+    - *책* : PDF, HTML, ePub, gitbook.io 기반 웹사이트, 깃 리포지토리, 등.
+    - *강좌* : 여기서 강좌는 책이 아닌 교육 도구르 칭합니다. [강좌 예시](http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-006-introduction-to-algorithms-fall-2011/).
+    - *상호작용을 할 수 있는 강좌* : 사용자가 코드를 입력하거나 명령어를 입력하여 평가을 받을 수 있는 웹사이트를 칭합니다(평가는 채점이 아닙니다). 예시: [Try Haskell](http://tryhaskell.org), [Try Github](http://try.github.io).
+    - *팟캐스트와 화면 녹화*
+    - *문제집 & 경쟁 하며 배우느 프로그래밍* : 문제를 품으로서 프로그래밍 실력을 향상시키는데 도움을 주는 소프트웨어 또는 웹사이트를 칭합니다. 해당 소프트웨어 또는 웹사이트는 동료가 주체가 되는 코드 검토를 포함 할 수 있습니다.
+
+4. 아래의 [가이드라인](#가이드라인) 을 참조하고 [마크다운 규격](#규격) 을 준수하여 주십시오.
+
+5. 깃허브 액션이 각각의 리스트가 오름차순인지, 또하 규격이 준수되었는지 검수 할 것입니다. 각 제출이 검수를 통과하는지 확인해주십시오.
+
+### 가이드라인
+- 책이 무료인 반드시 확인 해 주십시오. 해당 책이 무료라고 생각하는 이유를 PR의 comment에 포함하는 것은 관리자들에게 큰 도움이 됩니다.
+- 저희는 Google Drive, Dropbox, Mega, Scribd, Issuu 또는 유사한 파일 공유 시스템에 업로드된 파일들을 수락하지 않습니다.
+- 바로가기를 오름차순으로 정렬해 주십시오. 만약 당신이 오름차순이 아닌 파일을 발견한다면, 수정후 PR을 보내주세요.
+- 가능한 가장 원작자에 가까운 바로가기를 사용해주세요(작가의 웹사이트가 편집자의 웹사이트보다 낫고, 제 3자의 웹사이트보다는 편집자의 것이 낫습니다).
+- 동일한 내용으 포함한다는 전 하에 `https` 주소를 `http`주소보다 우선시 해주십시오
+- 루트 도메인을 사용할때는, 마지막에 붙는 /를 배제하여주십시오. (`http://example.com` 가 `http://example.com/` 보다 낫습니다)
+- 모든 경우에 더 짧은 링크를 선호합니다: `http://example.com/dir/` 가 `http://example.com/dir/index.html`보다 낫지만, URL 단추 서비스를 사용하지 마십시오.
+- 대부분의 경우에 버전이 명시된 웹사이트보다는 현행 버젼 웹사이트를 선호합니다 (`http://example.com/dir/book/current/`가 `http://example.com/dir/book/v1.0.0/index.html`보다 낫습니다)
+- 만약 해당 바로가기의 인증서가 만료되었다면:
+    1. `http` 형식으로 *대치 하십시오*
+    2. `http` 버젼이 존재하지 않는다면, 기존의 링크를 사용하십시오. `https`형식또한 예외를 추가한다면 사용할 수 있습니다.
+    3. 이외의 경우에 *제외하십시오*
+- 만약 바로가기가 여러 형식으로 존재한다면, 각각을 쪽지와 함께 모두 첨부해주세요.
+- 만약 자료가 여러 사이트에 분산되어 있다면, 가장 믿을 수 있는 바로가기를 첨부해주세요. 만약 각각의 바로가기가 다른 버젼으로 향한다면, 쪽지와 함께 모두 포함하십시오. (참고: [Issue #2353](https://github.com/EbookFoundation/free-programming-books/issues/2353) 해당문서는 규격에 대해 설명합니다.)
+- 대량의 자료를 포함한 하나의 커밋보다는 작은 변화를 포함하는 여러개의 커밋이 선호됩니다.
+- 만약 오래된 책이라면, 출판일을 제목과 함께 포함하세요.
+- 작가(들)의 이름을 명시하십시오. "et al."을 사용하여 단축 할 수 있습니다.
+- 만약 책이 아직 완결되지 않았다면, [아래](#in_process)에 명시되어 있다시피, "in progress" 표시를 추가하십시오.
+- 만약 이메일 주소 또는 계정 생성이 다운로드 이전에 요청된다면, 별도의 노트를 첨부하세요.
+
+### 규격
+- 모든 목록은 `.md`파일 형식 이어야 합니다. 해당 형식의 문법은 간단하며, [Markdown](https://guides.github.com/features/mastering-markdown/) 에서 찾아 볼 수 있습니다.
+- 모든 목록은 목차와 함께 시작해야 합니다. 각 항목을 목차에 연결하는 것이 목표입니다. 오름차순으로 정렬되어 있어야 합니다.
+- 각 섹션은 3단계 헤딩을 사용합니다 (`###`). 하위 섹션은 4단계 헤딩을 사용합니다 (`####`).
+
+반드시 포함하여야 하는 항목들:
+- 마지막 바로가기와 새로운 섹션 사이의 줄바꿈 `2`회
+- 머리말과 섹션의 첫 바로가기 사이의 줄바꿈 `1`회
+- 두 바로가기 사이의 줄바꿈 `0`회
+- `.md` 파일의 마지막에 `1`회의 줄바꿈
+
+예시:
+
+    [...]
+    * [An Awesome Book](http://example.com/example.html)
+                                    (blank line)
+                                    (blank line)
+    ### Example
+                                    (blank line)
+    * [Another Awesome Book](http://example.com/book.html)
+    * [Some Other Book](http://example.com/other.html)
+
+- `]` 와 `(` 사이에 공백을 넣지 마십시오:
+
+```
+BAD : * [Another Awesome Book] (http://example.com/book.html)
+GOOD: * [Another Awesome Book](http://example.com/book.html)
+```
+
+- 저자를 표시할 경우, ` - `를 사용하십시오 (띄어쓰기 - 띄어쓰기):
+
+```
+BAD : * [Another Awesome Book](http://example.com/book.html)- John Doe
+GOOD: * [Another Awesome Book](http://example.com/book.html) - John Doe
+```
+
+- 바로가기와 형식 사이에는 공백을 삽입 하십시오:
+
+```
+BAD : * [A Very Awesome Book](https://example.org/book.pdf)(PDF)
+GOOD: * [A Very Awesome Book](https://example.org/book.pdf) (PDF)
+```
+
+- 저자는 형식 전에 옵니다:
+
+```
+BAD : * [A Very Awesome Book](https://example.org/book.pdf)- (PDF) Jane Roe
+GOOD: * [A Very Awesome Book](https://example.org/book.pdf) - Jane Roe (PDF)
+```
+
+- 여러가지의 파일 형식이 존재할떄:
+
+```
+BAD : * [Another Awesome Book](http://example.com/)- John Doe (HTML)
+BAD : * [Another Awesome Book](https://downloads.example.org/book.html)- John Doe (download site)
+GOOD: * [Another Awesome Book](http://example.com/) - John Doe (HTML) [(PDF, EPUB)](https://downloads.example.org/book.html)
+```
+
+- 오래된 책들은 출판 년도를 포함하세요:
+
+```
+BAD : * [A Very Awesome Book](https://example.org/book.html) - Jane Roe - 1970
+GOOD: * [A Very Awesome Book (1970)](https://example.org/book.html) - Jane Roe
+```
+
+<a name="in_process"></a>
+- 작성중인 책:
+
+```
+GOOD: * [Will Be An Awesome Book Soon](http://example.com/book2.html) - John Doe (HTML) (:construction: *in process*)
+```
+
+### 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.
+- 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.
+
+#### 장르
+
+자료가 어떤 장르에 속하는지 결정하는 첫번째 방법은 해당 자료의 분류에 따르는 것입니다.
+
+##### 기술하지않는 장르
+
+인터넷에는 너무 다양하고 정확하지않은 자료들이 있기에, 저희는 다음 장르를 포함하지 않습니다:
+
+- 블로그
+- 블로그 게시글
+- 기사
+- (목록에 포함된 장르를 대량 포함하지 않는 경우) 웹사이트
+- 강좌가 아닌 영상
+- 책의 목차
+- 채팅 채널
+- 책의 미리보기
+- 슬랙, 전자메일
+
+상기된 목록은 최종적이지 않으며, 이슈를 생성하여 기여자들이 제안을 할 수 있습니다.
+
+
+##### 책 vs. 다른 자료
+
+저희는 자료가 얼마나 책에 가까운지는 중요하지 않습니다. 다음의 항목을을 포함한다면, 책으로 간주됩니다:
+
+- ISBN의 존재 여부 (International Standard Book Number)
+- 목차가 존재하는가
+- 다운로드를 받을 수 있는가 (특히 ePub 형식)
+- 개정판이 있는가
+- 상호작용을 하지않는가
+- 분명한 하나의 주제가 있는가
+- 스스로 내용을 포함하고 있는가
+
+저희가 인정하는 책들은 위 항목을 모두 포함하지 않을 수 있으며, 최종적으로는 내용에 의해 결정됩니다.
+
+
+##### 책 vs. 강좌
+
+때에 따라 이 둘은 구분하기 어려울 수 있습니다.
+
+강좌는 종종 책을 보조교재로 사용하는데, 이것은 상기한 책의 특성에 의해 목록에 추가 될 수 있습니다. 이 보조교재에는 종종 강의 노트, 연습 문제, 시험, 등등이 포함됩니다. 영상/강의 하나는 강좌로 간주되지 않습니다. 또한, 파워포인트는 강좌가 아닙니다.
+
+##### 상호작용 강의 vs. 다른 자료
+
+만약 강의가 인쇄되어서도 사용 될 수 있다면, 상호작용 강의에 포함되지 않습니다.
+
+
+### 자동화
+
+- 규격 규칙은 [GitHub Actions](https://github.com/features/actions)에 의해 [fpb-lint](https://github.com/vhf/free-programming-books-lint)를 사용하여 강제됩니다 (see [.github/workflows/fpb-lint.yml](.github/workflows/fpb-lint.yml))
+- 바로가기 주소 검증은 [awesome_bot](https://github.com/dkhamsing/awesome_bot)를 이용합니다
+- 바로가기 주소 검증을 위해 커밋 메시지에 `check_urls=file_to_check`을 포함해 주세요:
+
+```
+check_urls=free-programming-books.md free-programming-books-en.md
+```
+
+- 각 입력을 공백으로 구문하여 하나 이상의 파일을 검사 할 수 있습니다.
+- 만약 하나 이상의 파일을 검사한다면, 검사 결과는 마지막 파일의 검사 결과가 표시됩니다. 이 특성으로 인하여 통과를 받았더라도 관리자에 의하여 최종 승인이 보류 될 수 있습니다. 정확한 결과를 확인 하려면, "Show all checks" -> "Details"로 가세요.

+Dobrodošli v zbirki Free-Programming-Books! Lepo pozdravljeni vsi novi programerji - tudi tisti, ki boste na Githubu ustvarili vaš prvi zahtevek potega (pull-request). Če ste eden izmed njih, vam pri tem lahko pomaga nekaj virov:

+* [About Pull Requests](https://help.github.com/articles/about-pull-requests/)

+
+
+Ne oklevajte in postavljajte vprašanja; vsak programer je enkrat začel s svojim prvim PR-om. Vi ste lahko naš tisoči!
+
+Tudi če ste izkušeni na področju programiranja odprte kode, se bodo zagotovo našle zadeve, ki vas lahko malce zaustavijo. Ko oddate PR, bo GitHub Actions zagnal pregledovalnik, ki pogosto najde manjše težave z razmikom ali abecedo. Če se vam prikaže zeleni gumb, je vse pripravljeno za pregled. Če se zeleni gumb ne prikaže, kliknite »Podrobnosti« pod kljukico, ki je ugotovila, kaj pregledovalniku ni bilo všeč. Odpravite težavo in dodajte zahtevo (commit) v PR.
