 # json
-方便的c++JSON库<br>
+使用 C++ 特性编写的 JSON 库  
 [简体中文](README.md) | [English](README_EN.md)
+
+# 前言
+为什么要写这样一个JSON库？github上目前有很多大型的JSON解析库，如RapidJSON、jsoncpp、nlohmann_json，但由于历史等不可抗力原因，它们有着各自的缺点与不足，各种繁多的代码堆积，导致维护困难，我致力于打造一个代码最简单，速度快，便携的JSON库。
+
 # 特点
-1. 简单易用
-2. 内存友好
-3. 效率高
-4. 支持解析时报错
+1. 百般打磨的API
+2. 使用std::variant进行操作，内存友好
+3. 拥有比nlohmann稍高的效率
+4. 代码遵循`Google C++ Style`
+
 # 用法
-1. 将json.cpp和json.h添加到你的项目
-2. 将项目的语言标准调整到c++17
-3. 包括json.h文件
-4. 接下来就可以使用本json库了
+1. 将`json.cpp`和`json.h`添加到你的项目
+2. 将项目的语言标准调整到`c++17`或者更新的版本
+3. 在你的`.c`或者`.cpp`文件包括`json.h`

 当然你也可以用Value::dump()来实现此功能  
 如果要配置序列化模式，就得用此例子

 # json
-Convenient c++JSON library<br>
+JSON library written with C++ features  
 [简体中文](README.md) | [English](README_EN.md)
+
+# Preface
+Why write such a JSON library? github currently has a lot of large JSON parsing library, such as RapidJSON, jsoncpp, nlohmann_json, but due to history and other force majeure reasons, they have their own shortcomings and shortcomings, a variety of a wide range of code pile up, resulting in maintenance difficulties, I am committed to creating a code the most simple, fast, portable JSON library. Fast, portable JSON library.
+
 # Features
-1. Simple and easy to use
-2. Memory friendly
-3. High efficiency
-4. Supports error reporting when parsing
+1. a hundred polished API
+2. use std::variant for operations, memory-friendly
+3. has a slightly higher efficiency than nlohmann
+4. The code follows `Google C++ Style`
+
+# Usage
+1. add `json.cpp` and `json.h` to your project
+2. adjust the project's language standard to `c++17` or newer
+3. Include `json.h` in your `.c` or `.cpp` file
+
+# Documentation
+## Main classes
+* Value
+Used to store, query and modify JSON data
+* Parser
+Used to parse a JSON string into Value
+```cpp
+Parser p.
+Value v.
+if (!p.parse(s, v))
+	cout << p.getError() << endl.
+```
+* Writer
+Used to serialize Value objects into JSON strings
+```cpp
+Writer w.
+Value v.
+w.writeValue(v).
+cout << w.getOutput() << endl.
+```
+Of course you can also use Value::dump() for this function  
+If you want to configure serialization mode, you have to use this example
