+## 怎么给 Weex Ui 贡献代码
+
+**欢迎大家给 Weex Ui 提交 [pull requests](https://github.com/alibaba/weex-ui/compare/) 来修复 Bug、新增组件、完善文档案例已经任何优化建议都可以的**。
+
+## Branch 管理
+
+```
+master
+ ↑
+dev         <--- Develop/PR
+```
+
+- `dev` 分支
+  - 所有的开发均在 dev 分支进行
+  - 提 PR 时候请提交到 dev 分支
+- `master` 分支
+  - `master` 是稳定不改的分支,不会在上面进行代码开发
+  - 在 dev 分支 publish 后会 merge 到 master,同时打对应 tag
+
+## Commit 格式
+
+```
+[{action}] {description}
+```
+
+- `{action}`
+  - `+` 新增功能
+  - `!` 更新或者修复 bug
+  - `-` 移除功能
+- `{description}`
+  - 尽可能详细的描述就好
+
+for example:
+
+- [+] 列表选项新增拖拽功能
+- [!] 修复输入框长按闪烁的问题
+
+## 更多
+
+- 很推荐在提交 PR 前,先在钉钉群里进行讨论,已防止此功能已经有同学在开发了
+- 但是如何是想修复文档和明显代码错误,直接提交 PR 就好
