+To bind a request body into a type, use model binding. We currently support binding of JSON, XML, YAML and standard form values (foo=bar&boo=baz).
 
 Gin uses [**go-playground/validator.v8**](https://github.com/go-playground/validator) for validation. Check the full docs on tags usage [here](http://godoc.org/gopkg.in/go-playground/validator.v8#hdr-Baked_In_Validators_and_Tags).

 Also, Gin provides two sets of methods for binding:
 - **Type** - Must bind
-  - **Methods** - `Bind`, `BindJSON`, `BindXML`, `BindQuery`
+  - **Methods** - `Bind`, `BindJSON`, `BindXML`, `BindQuery`, `BindYAML`
   - **Behavior** - These methods use `MustBindWith` under the hood. If there is a binding error, the request is aborted with `c.AbortWithError(400, err).SetType(ErrorTypeBind)`. This sets the response status code to 400 and the `Content-Type` header is set to `text/plain; charset=utf-8`. Note that if you try to set the response code after this, it will result in a warning `[GIN-debug] [WARNING] Headers were already written. Wanted to override status code 400 with 422`. If you wish to have greater control over the behavior, consider using the `ShouldBind` equivalent method.

   - **Behavior** - These methods use `ShouldBindWith` under the hood. If there is a binding error, the error is returned and it is the developer's responsibility to handle the request and error appropriately.
 
 When using the Bind-method, Gin tries to infer the binder depending on the Content-Type header. If you are sure what you are binding, you can use `MustBindWith` or `ShouldBindWith`.

+# How to build one effective middleware?
+
+## Consitituent part
+
+The middleware has two parts:
+
+  - part one is what is executed once, when you initialize your middleware. That's where you set up all the global objects, logicals etc. Everything that happens one per application lifetime.
+
+  - part two is what executes on every request. For example, a database middleware you simply inject your "global" database object into the context. Once it's inside the context, you can retrieve it from within other middlewares and your handler function.
+
+```go
+func funcName(params string) gin.HandlerFunc {
+    // <---
+    // This is part one
+    // --->
+    // The follow code is an example
+    if err := check(params); err != nil {
+        panic(err)
+    }
+
+    return func(c *gin.Context) {
+        // <---
+        // This is part two
+        // --->
+        // The follow code is an example
+        c.Set("TestVar", params)
+        c.Next()    
+    }
+}
+```
+
+## Execution process
+
+Firstly, we have the follow example code:
+
+```go
+func main() {
+	router := gin.Default()
+
+	router.Use(globalMiddleware())
+
+	router.GET("/rest/n/api/*some", mid1(), mid2(), handler)
+
+	router.Run()
+}
+
+func globalMiddleware() gin.HandlerFunc {
+	fmt.Println("globalMiddleware...1")
+
+	return func(c *gin.Context) {
+		fmt.Println("globalMiddleware...2")
+		c.Next()
+		fmt.Println("globalMiddleware...3")
+	}
+}
+
+func handler(c *gin.Context) {
+	fmt.Println("exec handler.")
+}
+
+func mid1() gin.HandlerFunc {
+	fmt.Println("mid1...1")
+
+	return func(c *gin.Context) {
+
+		fmt.Println("mid1...2")
+		c.Next()
+		fmt.Println("mid1...3")
+	}
+}
+
+func mid2() gin.HandlerFunc {
+	fmt.Println("mid2...1")
+
+	return func(c *gin.Context) {
+		fmt.Println("mid2...2")
+		c.Next()
+		fmt.Println("mid2...3")
+	}
+}
+```
+
+According to [Consitituent part](#consitituent-part) said, when we run the gin process, **part one** will execute firstly and will print the follow information:
+
+```go
+globalMiddleware...1
+mid1...1
+mid2...1
+```
+
+And init order are:
+
+```go
+globalMiddleware...1
+    |
+    v
+mid1...1
+    |
+    v
+mid2...1
+```
+
+When we curl one request `curl -v localhost:8080/rest/n/api/some`, **part two** will execute their middleware and output the following information:
+
+```go
+globalMiddleware...2
+mid1...2
+mid2...2
+exec handler.
+mid2...3
+mid1...3
+globalMiddleware...3
+```
+
+In other words, run order are:
+
+```go
+globalMiddleware...2
+    |
+    v
+mid1...2
+    |
+    v
+mid2...2
+    |
+    v
+exec handler.
+    |
+    v
+mid2...3
+    |
+    v
+mid1...3
+    |
+    v
+globalMiddleware...3
