+# Getting start with API application development
+Go is very good for developing API applications which I think is the biggest strength compare to other dynamic languages. Beego provides powerful and quick setup tool for developing API applications, which gives you more focus on business logic.
+
+
+## Quick setup
+bee can setup a API application very quick by executing commands under any `$GOPATH/src`. 
+
+`bee api beeapi`
+
+## Application directory structure
+
+ ```
+├── conf
+│   └── app.conf
+├── controllers
+│   └── default.go
+├── models
+│    └── object.go
+└── main.go	
+```
+
+## Source code explanation
+
+- app.conf has following configuration options for your API applications:
+
+	- autorender = false  // Disable auto-render since API applications don't need.
+	- copyrequestbody = true  // RESTFul applications sends raw body instead of form, so we need to read body specifically.
+
+- main.go is for registering routers of RESTFul.
+
+		beego.RESTRouter("/object", &controllers.ObejctController{})
+
+Match rules as follows:
+
+<table>
+<tr>
+	<th>URL</th>					<th>HTTP Verb</th>				<th>Functionality</th>
+</tr>
+<tr>	
+	<td>/object</td>				<td>POST</td>					<td>Creating Objects</td>
+</tr>
+<tr>	
+	<td>/object/objectId</td>	<td>GET</td>					<td>Retrieving Objects</td>
+</tr>
+<tr>	
+	<td>/object/objectId</td>	<td>PUT</td>						<td>Updating Objects</td>
+</tr>
+<tr>	
+	<td>/object</td>				<td>GET</td>						<td>Queries</td>
+</tr>
+<tr>	
+	<td>/object/objectId</td>	<td>DELETE</td>					<td>Deleting Objects</td>
+</tr>
+</table>
+
+- ObejctController implemented corresponding methods:
+
+	type ObejctController struct {
+		beego.Controller
+	}
+	
+	func (this *ObejctController) Post(){
+		
+	}
+	
+	func (this *ObejctController) Get(){
+		
+	}
+	
+	func (this *ObejctController) Put(){
+		
+	}
+	
+	func (this *ObejctController) Delete(){
+		
+	}
+
+- models implemented corresponding object operation for adding, deleting, updating and getting.
+
+## Test
+
+- Add a new object:
+	
+		curl -X POST -d '{"Score":1337,"PlayerName":"Sean Plott"}' http://127.0.0.1:8080/object
+		
+	Returns a corresponding objectID:astaxie1373349756660423900
+	
+- Query a object:
+
+	`curl -X GET http://127.0.0.1:8080/object/astaxie1373349756660423900`
+	
+- Query all objects:
+
+	`curl -X GET http://127.0.0.1:8080/object`
+
+- Update a object:
+
+	`curl -X PUT -d '{"Score":10000}'http://127.0.0.1:8080/object/astaxie1373349756660423900`
+
+- Delete a object:
+
+	`curl -X DELETE http://127.0.0.1:8080/object/astaxie1373349756660423900`
