+Electron은 JavaScript, HTML 그리고 CSS를 이용하여 Cross-Platform 데스크톱 어플리케이션을 개발할 수 있도록 해주는 프레임워크입니다. 이 프레임워크는 [io.js](http://iojs.org) 와
+[Chromium](http://www.chromium.org) 을 기반으로 만들어 졌으며 [Atom Editor](https://github.com/atom/atom) 에 사용되고 있습니다.
+
+Electron에 대한 중요한 알림을 받으려면 Twitter에서 [@ElectronJS](https://twitter.com/electronjs)를 Follow하세요.
+
+## 다운로드
+
+Linux, Windows, Mac용으로 미리 빌드된 Electron 바이너리와 디버그 심볼이 준비되어 있습니다. [releases](https://github.com/atom/electron/releases) 페이지에서 받아 볼 수 있습니다.
+
+또한 [`npm`](https://docs.npmjs.com/)을 이용하여 미리 빌드된 Electron 바이너리를 받을 수 있습니다:
+
+```sh
+# $PATH에 `electron`을 등록하고 전역에 설치합니다.
+npm install electron-prebuilt -g
+
+# 개발용 dependency로 설치합니다.
+npm install electron-prebuilt --save-dev
+```
+
+### 미러
+
+- [China](https://npm.taobao.org/mirrors/electron)
+
+## 참조문서
+
+[docs](https://github.com/atom/electron/tree/master/docs/README-ko.md) 에 프레임워크 사용 가이드와 API 레퍼런스가 있습니다.
+추가적으로 Electron을 빌드 하는 방법과 프로젝트에 기여하는 방법도 문서에 포함되어 있으니 참고하기 바랍니다.
+
+## 커뮤니티
+
+[Atom 포럼내의 `electron` 카테고리](http://discuss.atom.io/category/electron) 와 Freenode `#atom-shell` 채팅채널이 있습니다.
+
+[awesome-electron](https://github.com/sindresorhus/awesome-electron) 에 커뮤니티가 운영중인 유용한 예제 앱과 툴, 리소스가 있으니 한번 탐색해 보시기 바랍니다.
