 ### 代码结构
 Network部分使用 Kotlin 完成(因为kt有对 unsigned byte 的支持).  
-与插件相关性强(或其他在二次开发中容易接触的部分)均使用 Java 完成,

 同时也会针对kotlin提供优化的方法调用. 例如对'+'操作符的重载: `String+BufferedImage+QQ.At+Face+URL+String+File` 将会被自动处理为String消息.

 /**
+ * Mirai 的网络处理器, 它处理所有数据包([Packet])的发送和接收.
+ * [RobotNetworkHandler] 是全程异步和线程安全的.
+ *
+ * [RobotNetworkHandler] 由 2 个模块构成:
+ * - [SocketHandler]: 处理数据包底层的发送([ByteArray])
+ * - [PacketHandler]: 制作 [Packet] 并传递给 [SocketHandler] 继续处理; 分析来自服务器的数据包并处理
+ *
+ * 其中, [PacketHandler] 由 4 个子模块构成:
+ * - [DebugHandler] 输出 [Packet.toString]
+ * - [LoginHandler] 处理 touch/login/verification code 相关
+ * - [MessageHandler] 处理消息相关(群消息/好友消息)([ServerEventPacket])
+ * - [ActionHandler] 处理动作相关(踢人/加入群/好友列表等)
+ *
  * A RobotNetworkHandler is used to connect with Tencent servers.
