+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at [electron@github.com](mailto:electron@github.com). All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.

+# Electron에 기여하기
+
+:+1::tada: 먼저, 기여에 관심을 가져주셔서 감사합니다! :tada::+1:
+
+이 프로젝트는 기여자 규약인 [행동강령](CODE_OF_CONDUCT.md)을 준수합니다. 따라서 이
+프로젝트의 개발에 참여하려면 이 규약을 지켜야 합니다. 받아들일 수 없는 행위를 발견했을
+경우 atom@github.com로 보고하세요.
+
+다음 항목들은 Electron에 기여하는 가이드라인을 제시합니다.
+참고로 이 항목들은 그저 가이드라인에 불과하며 규칙이 아닙니다. 따라서 스스로의 적절한
+판단에 따라 이 문서의 변경을 제안할 수 있으며 변경시 pull request를 넣으면 됩니다.
+
+## 이슈 제출
+
+* [여기](https://github.com/electron/electron/issues/new)에서 새로운 이슈를 만들 수
+있습니다. 하지만 이슈를 작성하기 전에 아래의 항목들을 숙지하고 가능한한 이슈 보고에
+대해 최대한 많은 정보와 자세한 설명을 포함해야 합니다. 가능하다면 다음 항목을 포함해야
+합니다:
+  * 사용하고 있는 Electron의 버전
+  * 현재 사용중인 운영체제
+  * 가능하다면 무엇을 하려고 했고, 어떤 결과를 예측했으며, 어떤 것이 예측된대로
+  작동하지 않았는지에 대해 서술해야 합니다.
+* 추가로 다음 사항을 준수하면 이슈를 해결하는데 큰 도움이 됩니다:
+  * 스크린샷 또는 GIF 애니메이션 이미지들
+  * 터미널에 출력된 에러의 내용 또는 개발자 도구, 알림창에 뜬 내용
+  * [Cursory search](https://github.com/electron/electron/issues?utf8=✓&q=is%3Aissue+)를
+  통해 이미 비슷한 내용의 이슈가 등록되어있는지 확인
+
+## Pull Request 하기
+
+* 가능한한 스크린샷과 GIF 애니메이션 이미지를 pull request에 추가
+* JavaScript, C++과 Python등
+[참조 문서에 정의된 코딩스타일](/docs-translations/ko-KR/development/coding-style.md)을
+준수
+* [문서 스타일 가이드](/docs-translations/ko-KR/styleguide.md)에 따라 문서를
+[Markdown](https://daringfireball.net/projects/markdown) 형식으로 작성.
+* 짧은, 현재 시제 커밋 메시지 사용. [커밋 메시지 스타일 가이드](#git-커밋-메시지)를
+참고하세요
+
+## 스타일 가이드
+
+### 공통 코드
+
+* 파일 마지막에 공백 라인(newline) 추가
+* 다음 순서에 맞춰서 require 코드 작성:
+  * Node 빌트인 모듈 (`path` 같은)
+  * Electron 모듈 (`ipc`, `app` 같은)
+  * 로컬 모듈 (상대 경로상에 있는)
+* 다음 순서에 맞춰서 클래스 속성 지정:
+  * 클래스 메서드와 속성 (메서드는 `@`로 시작)
+  * 인스턴스 메서드와 속성
+* 플랫폼 종속적인 코드 자제:
+  * 파일 이름 결합시 `path.join()`을 사용.
+  * 임시 디렉터리가 필요할 땐 `/tmp` 대신 `os.tmpdir()`을 통해 접근.
+* 명시적인 함수 종료가 필요할 땐 `return` 만 사용.
+  * `return null`, `return undefined`, `null`, 또는 `undefined` 사용 X
+
+### Git 커밋 메시지
+
+* 현재 시제 사용 ("Added feature" 대신 "Add feature" 사용)
+* 명령법(imperative mood) 사용 ("Moves cursor to..." 대신 "Move cursor to..." 사용)
+* 첫 줄은 72자에 맞추거나 그 보다 적게 제한
+* 자유롭게 필요에 따라 이슈나 PR링크를 참조
+* 단순한 문서 변경일 경우 `[ci skip]`을 커밋 메시지에 추가
+* 커밋 메시지의 도입부에 의미있는 이모티콘 사용:
+  * :art: `:art:` 코드의 포맷이나 구조를 개선(추가)했을 때
+  * :racehorse: `:racehorse:` 성능을 개선했을 때
+  * :non-potable_water: `:non-potable_water:` 메모리 누수를 연결했을 때
+  * :memo: `:memo:` 문서를 작성했을 때
+  * :penguin: `:penguin:` Linux에 대한 패치를 했을 때
+  * :apple: `:apple:` macOS에 대한 패치를 했을 때

+# Contributing to Electron
+
+:+1::tada: First off, thanks for taking the time to contribute! :tada::+1:
+
+This project adheres to the Contributor Covenant [code of conduct](CODE_OF_CONDUCT.md).
+By participating, you are expected to uphold this code. Please report unacceptable
+behavior to atom@github.com.
+
+The following is a set of guidelines for contributing to Electron.
+These are just guidelines, not rules, use your best judgment and feel free to
+propose changes to this document in a pull request.
+
+## Submitting Issues
+
+* You can create an issue [here](https://github.com/electron/electron/issues/new),
+but before doing that please read the notes below and include as many details as
+possible with your report. If you can, please include:
+  * The version of Electron you are using
+  * The operating system you are using
+  * If applicable, what you were doing when the issue arose and what you
+  expected to happen
+* Other things that will help resolve your issue:
+  * Screenshots and animated GIFs
+  * Error output that appears in your terminal, dev tools or as an alert
+  * Perform a [cursory search](https://github.com/electron/electron/issues?utf8=✓&q=is%3Aissue+)
+  to see if a similar issue has already been submitted
+
+## Submitting Pull Requests
+
+* Include screenshots and animated GIFs in your pull request whenever possible.
+* Follow the JavaScript, C++, and Python [coding style defined in docs](/docs/development/coding-style.md).
+* Write documentation in [Markdown](https://daringfireball.net/projects/markdown).
+  See the [Documentation Styleguide](/docs/styleguide.md).
+* Use short, present tense commit messages. See [Commit Message Styleguide](#git-commit-messages).
+
+## Styleguides
+
+### General Code
+
+* End files with a newline.
+* Place requires in the following order:
+  * Built in Node Modules (such as `path`)
+  * Built in Electron Modules (such as `ipc`, `app`)
+  * Local Modules (using relative paths)
+* Place class properties in the following order:
+  * Class methods and properties (methods starting with a `@`)
+  * Instance methods and properties
+* Avoid platform-dependent code:
+  * Use `path.join()` to concatenate filenames.
+  * Use `os.tmpdir()` rather than `/tmp` when you need to reference the
+    temporary directory.
+* Using a plain `return` when returning explicitly at the end of a function.
+  * Not `return null`, `return undefined`, `null`, or `undefined`
+
+### Git Commit Messages
+
+* Use the present tense ("Add feature" not "Added feature")
+* Use the imperative mood ("Move cursor to..." not "Moves cursor to...")
+* Limit the first line to 72 characters or less
+* Reference issues and pull requests liberally
+* When only changing documentation, include `[ci skip]` in the commit description
+* Consider starting the commit message with an applicable emoji:
+  * :art: `:art:` when improving the format/structure of the code
+  * :racehorse: `:racehorse:` when improving performance
+  * :non-potable_water: `:non-potable_water:` when plugging memory leaks
+  * :memo: `:memo:` when writing docs
+  * :penguin: `:penguin:` when fixing something on Linux
+  * :apple: `:apple:` when fixing something on macOS
+  * :checkered_flag: `:checkered_flag:` when fixing something on Windows
+  * :bug: `:bug:` when fixing a bug
+  * :fire: `:fire:` when removing code or files
+  * :green_heart: `:green_heart:` when fixing the CI build
+  * :white_check_mark: `:white_check_mark:` when adding tests
+  * :lock: `:lock:` when dealing with security
+  * :arrow_up: `:arrow_up:` when upgrading dependencies
+  * :arrow_down: `:arrow_down:` when downgrading dependencies
