+# Contributing to beego
+
+beego is an open source project.
+
+It is the work of hundreds of contributors. We appreciate your help!
+
+Here are instructions to get you started. They are probably not perfect, 
+please let us know if anything feels wrong or incomplete.
+
+## Contribution guidelines
+
+### Pull requests
+
+First of all. beego follow the gitflow. So please send you pull request 
+to **develop** branch. We will close the pull request to master branch.
+
+We are always happy to receive pull requests, and do our best to
+review them as fast as possible. Not sure if that typo is worth a pull
+request? Do it! We will appreciate it.
+
+If your pull request is not accepted on the first try, don't be
+discouraged! Sometimes we can make a mistake, please do more explaining 
+for us. We will appreciate it.
+
+We're trying very hard to keep beego simple and fast. We don't want it
+to do everything for everybody. This means that we might decide against
+incorporating a new feature. But we will give you some advice on how to 
+do it in other way.
+
+### Create issues
+
+Any significant improvement should be documented as [a GitHub
+issue](https://github.com/astaxie/beego/issues) before anybody
+starts working on it. 
+
+Also when filing an issue, make sure to answer these five questions:
+
+- What version of beego are you using (bee version)?
+- What operating system and processor architecture are you using?
+- What did you do?
+- What did you expect to see?
+- What did you see instead?
+
+### but check existing issues and docs first!
+
+Please take a moment to check that an issue doesn't already exist
+documenting your bug report or improvement proposal. If it does, it
+never hurts to add a quick "+1" or "I have this problem too". This will
+help prioritize the most common problems and requests.
+
+Also if you don't know how to use it. please make sure you have read though
+the docs in http://beego.me/docs

-beego is a Go Framework inspired by tornado and sinatra.
-
-It is a simple & powerful web framework.
+beego is used for rapid development of RESTful APIs, web apps and backend services in Go.
+It is inspired by Tornado, Sinatra and Flask. beego has some Go-specific features such as interfaces and struct embedding.
 
 More info [beego.me](http://beego.me)
 
+##Quick Start
+######Download and install
+
+    go get github.com/astaxie/beego
+
+######Create file `hello.go`
+```go
+package main

+import "github.com/astaxie/beego"
+
+func main(){
+    beego.Run()
+}
+```
+######Build and run
+```bash
+    go build hello.go
+    ./hello
+```
+######Congratulations! 
+You just built your first beego app.
