+### CPU 占用率保持工具使用说明：
+
+1. 将对应架构（amd64、arm64）的文件拷贝到需要的目录；
+2. 启动 screen 或者 tmux 进程
+3. 执行 `./cpulimit -l 20 -i ./keeper`
+  - `-l 20`: 想要限制的占用率
+  - `-i`: 限制对子进程也生效
+
+例如：
+
+```bash
+$ git clone https://git.ofcss.com/kairee/debian.git
+$ mv debian/bin/amd64 /usr/local/keeper
+$ screen -S cpukeeper
+$ cd /usr/local/keeper
+$ ./cpulimit -l 19 -i ./keeper
+```
+
+另外启动一个窗口，用 top 或者 htop（推荐）查看 CPU 占用率
