+Electron 프레임워크는 JavaScript, HTML 그리고 CSS를 사용하여 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 받고 싶다면 Twitter에서 [@ElectronJS](https://twitter.com/electronjs)를 팔로우 하세요.
+
+이 프로젝트는 기여자 규약 1.2를 준수합니다. 이 프로젝트에 참여할 때 코드를 유지해야 합니다. 받아들일 수 없는 행동은 atom@github.com로 보고 하십시오.
+
+## 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 통해 미리 빌드된 Electron 바이너리를 받을 수도 있습니다:
+
+```sh
+# $PATH에 `electron` 커맨드를 등록하고 전역에 설치합니다.
+npm install electron-prebuilt -g
+
+# 개발 의존성 모듈 형태로 설치합니다.
+npm install electron-prebuilt --save-dev
