+# 目前开发进度
+
+## 服务端
+
+- 可以实现接受用户的登录注册请求
+- 并且可以显示注册用户和当前在线用户
+
+## 客户端
+
+- 实现功能菜单选择
+- 实现登录注册的逻辑，可以与服务端通信
+
+# 待实现的功能
+
+## 服务端
+
+- 将注册用户的信息持久化存储
+- 实现在线用户存活检测
+  - 客户端3秒发送hello消息
+  - 9秒未搜到客户端的hello消息，判断该用户已经下线
+- 实现聊天功能
+  - 将需要发送到对应客户端的消息存在客户端对象中
+  - 当收到客户端hello消息的时候，将未读消息发送过去
+
+## 客户端
+
+- 发送聊天信息
+- 接受未读消息
