 # 简介
+
 使用安卓的DeviceAdmin和DeviceOwner API管理你的设备！
-即将加入的功能：安装应用、卸载应用、清空应用数据
+
+欢迎大家提交Issue
+
+### 功能
+
+- 添加用户限制
+    - 禁止使用蓝牙
+    - 禁止使用WiFi
+    - 禁止安装应用
+    - ......
+- 管理应用
+    - 隐藏应用
+    - 停用应用
+    - 禁止卸载应用
+    - ......
+- 设备控制
+    - 禁用相机
+    - 禁止截屏
+    - 隐藏状态栏
+
+这个应用需要的权限十分敏感，如果操作不慎，可能会让你的设备丢失数据或者让你无法解锁你的设备
+
+但是你无需担心，这个应用不是恶意软件
