+### 关于在Swift中使用MJExtension ‼️
+
+#### ‼️ `@objc` attributes should be added to class and property for declaration of Objc accessibility [在 Swift4 之后, 请在属性前加 `@objc` 修饰. 以保证 Swift 的属性能够暴露给 Objc 使用. ]‼️
+#### ‼️ Use `NSNumber` instead of `Bool`, which is not bridged to `BOOL`. [请勿使用 `Bool` 类型, 因为在 Swift 中并没有桥接该类型, 不能显式的对应 `BOOL`, 请使用 `NSNumber` 替代] ‼️

+# <a id="Getting_Started"></a> Getting Started【开始使用】
+
+## <a id="Features"></a> Features【能做什么】
+- MJExtension是一套字典和模型之间互相转换的超轻量级框架
+* `JSON` --> `Model`、`Core Data Model`
+* `JSONString` --> `Model`、`Core Data Model`
+* `Model`、`Core Data Model` --> `JSON`
+* `JSON Array` --> `Model Array`、`Core Data Model Array`
+* `JSONString` --> `Model Array`、`Core Data Model Array`
+* `Model Array`、`Core Data Model Array` --> `JSON Array`
+* Coding all properties of a model with only one line of code.
+    * 只需要一行代码，就能实现模型的所有属性进行Coding（归档和解档）
+
+## <a id="Installation"></a> Installation【安装】
+
+### From CocoaPods【使用CocoaPods】
+
+```ruby
+pod 'MJExtension'
+```
+
+### Manually【手动导入】
+- Drag all source files under folder `MJExtension` to your project.【将`MJExtension`文件夹中的所有源代码拽入项目中】
+- Import the main header file：`#import "MJExtension.h"`【导入主头文件：`#import "MJExtension.h"`】
+
+```objc
+MJExtension.h
+MJConst.h               MJConst.m
+MJFoundation.h          MJFoundation.m
+MJProperty.h            MJProperty.m

+- 因本人工作忙，没有太多时间去维护MJRefresh，在此向广大框架使用者说声：非常抱歉！😞
+- 现寻求志同道合的小伙伴一起维护此框架，有兴趣的小伙伴可以[发邮件](mailto:richermj123go@vip.qq.com)给我，非常感谢😊
+- 如果一切OK，我将开放框架维护权限（github、pod等）
+- 目前已经找到3位小伙伴(＾－＾)V
