 # Hello Minecraft! Launcher [![Build Status](https://travis-ci.org/huanghongxun/HMCL.svg?branch=master)](https://travis-ci.org/huanghongxun/HMCL)
 开源协议为GPL v3, 详情参见http://www.gnu.org/licenses/gpl.html
 
-## 介绍
+## Introduction
 
-HMCL是一个Minecraft启动器，支持Mod管理，游戏定制，自动安装，整合包制作，界面主题定制等功能。
-并且一天的使用次数在工作日时有40万左右、节假日有150万左右的使用次数，也就是说日活跃用户在10万以上。
-但是本项目的代码不够完善，希望有更多的人能加入HMCL的开发。
+HMCL is a Minecraft launcher which supports Mod management, game customizing, auto installing(Forge, LiteLoader and OptiFine), modpack creating, UI customizing and so on.
 
-## 贡献
-如果你很想为本项目贡献代码，这里有一些要求：
-* 开发环境为Netbeans 8.1
-* 编译器为Java 1.8，通过retrolambda兼容Java 1.7，所以请不要使用Java 8的新API（如Stream）
-* 请不要修改`gradle`文件
+## Contribution
+If you want to submit a pull request, there're some requirements:
+* IDE: Netbeans 8.1
+* Compiler: Java 1.8 and libraries only supports Java 1.7(because of retrolambda).
+* Do NOT modify `gradle` files.
 
-## 代码
-* 包 `org.jackhuang.hellominecraft.util` 为HMCL和HMCSM的共用工具代码
-* 包 `org.jackhuang.hellominecraft.launcher` 包含了HMCL的界面以及逻辑代码
-* 包 `org.jackhuang.hellominecraft.launcher.core` 为HMCL的启动核心
-* 包 `org.jackhuang.hellominecraft.launcher.api` 是HMCL为了便于定制提供的API，暂不支持加载插件
-* 包 `org.jackhuang.hellominecraft.svrmgr` 为HMCSM的所有代码
-* 文件夹 `HMCUtils/src/main/resources/org/jackhuang/hellominecraft/lang` 包含了HMCL和HMCSM使用的语言文件
