+## 卸载面板
+
+优先建议备份数据重装系统，这样可以保证系统纯净。
+
+如果你无法重装系统，请以`root`用户登录服务器，执行以下命令卸载面板：
+
+```shell
+bash <(curl -sSL https://dl.cdn.haozi.net/panel/uninstall_panel.sh)
+```
+
+卸载面板前请务必备份好所有数据，提前卸载面板全部插件。卸载后数据将**无法恢复**！
+

+## Uninstall Panel
+
+Recommended to back up data and reinstall the system first, so that the system can be kept clean.
+
+If you are unable to reinstall the system, log in to the server as the `root` user and execute the following command to uninstall the panel:
+
+```shell
+bash <(curl -sSL https://dl.cdn.haozi.net/panel/uninstall_panel.sh)
+```
+
+Before uninstalling the panel, please be sure to back up all data and uninstall all panel plugins in advance. The data will **not be recoverable** after uninstallation!
