 jsoniter (json-iterator) is fast and flexible JSON parser available in [Java](https://github.com/json-iterator/java) and [Go](https://github.com/json-iterator/go)
 
-# Why jsoniter?
+# Usage
 
-* Jsoniter is the fastest JSON parser. It could be up to 10x faster than normal parser, data binding included. Shameless self [benchmark](http://jsoniter.com/benchmark.html)
-* Extremely flexible api. You can mix and match three different styles: bind-api, any-api or iterator-api. Checkout your [api choices](http://jsoniter.com/api.html)
-* Unique iterator api can iterate through JSON directly, zero memory allocation! See how [iterator](http://jsoniter.com/api.html#iterator-api) works
+100% compatibility with standard lib

-
-# Bind-API is the best
-
-Bind-api should always be the first choice. Given this JSON document `[0,1,2,3]`
-
-Parse with Go bind-api
-
-```go
-import "github.com/json-iterator/go"
-iter := jsoniter.ParseString(`[0,1,2,3]`)
-var := iter.Read()
-fmt.Println(val)
+```
+import "encoding/json"
+json.Marshal(&data)
 ```
 
-# Iterator-API for quick extraction
+with 
 
-When you do not need to get all the data back, just extract some.
-
-Parse with Go iterator-api
-
-```go
+```
 import "github.com/json-iterator/go"
-iter := ParseString(`[0, [1, 2], [3, 4], 5]`)
-count := 0
-for iter.ReadArray() {
-    iter.Skip()
-    count++
-}
-fmt.Println(count) // 4
+jsoniter.Marshal(&data)
 ```
 
-# Any-API for maximum flexibility
+Replace
 
-Parse with Go any-api
-
-```go
-import "github.com/json-iterator/go"
-iter := jsoniter.ParseString(`[{"field1":"11","field2":"12"},{"field1":"21","field2":"22"}]`)
-val := iter.ReadAny()
-fmt.Println(val.ToInt(1, "field2")) // 22
+```
+import "encoding/json"
+json.Unmarshal(input, &data)
 ```
 
-Notice you can extract from nested data structure, and convert any type to the type to you want.
+with
+
+```
+import "github.com/json-iterator/go"
+jsoniter.Unmarshal(input, &data)
