-## Welcome to GitHub Pages
+## Rabbit ZooKeeper Extensions
 
-You can use the [editor on GitHub](https://github.com/RabbitTeam/zookeeper-client/edit/master/README.md) to maintain and preview the content for your website in Markdown files.
+该项目使用了 [Apache ZooKeeper .NET async Client](https://www.nuget.org/packages/ZooKeeperNetEx/) 组件，除提供了基本的zk操作还额外封装了常用的功能以更方便.net开发者更好的使用zookeeper。
+## 提供的功能
 
-Whenever you commit to this repository, GitHub Pages will run [Jekyll](https://jekyllrb.com/) to rebuild the pages in your site, from the content in your Markdown files.
+1. session过期重连
+2. 永久watcher
+3. 递归删除节点
+4. 递归创建节点
+5. 跨平台（支持.net core）
