 # netty-light-api-server
-如果你和我一样是一个两三年的后端开发，却是一个 java 新手，那么这个项目非常适合你来学习使用 java 构建后端服务。
-我希望通过该项目的构建重现我这一年 java 之旅，项目代码会从简单到复杂逐步构建，在适当的时机我会打上 tag，方便大家学习和阅读。
+A light java api server build on netty, if you are preparing for leaning java or netty, it's a nice gift for you.
+
+Version 1.0.0
+---
+In this version,there is no database, so you can run it directly.
+
+At first, java 8 should be supported in your server.
+
+There's two way to run it.
+
+1. Run `net.mengkang.netty.Server` in Intellij IDEA, Then you can visit http://localhost:8080/?api=user.get&uid=1 in your browser for test.
+
+2. Anther way is use java command line to run it. Download the `netty-light-api-server-1.0.0.zip` and unzip it , then run it like this
+```sh
+java -Dfile.encoding=UTF-8 -jar netty-light-api-server-1.0-SNAPSHOT.jar
+```
