 3. ARM 用户请使用此处的 [docker-compose.yml](https://github.com/Heavrnl/nexus-terminal/blob/main/doc/arm/docker-compose.yml)。由于 Apache Guacamole 未提供 guacd 的 ARM 架构镜像，所以禁用 RDP 功能，相关镜像暂时不再拉取。
 4. 由于本人手头没有arm机器，所以没有实际测试，运行中可能会有意想不到的bug

 3. ARM users, please use the [docker-compose.yml](https://github.com/Heavrnl/nexus-terminal/blob/main/doc/arm/docker-compose.yml) provided here. Since Apache Guacamole does not provide an ARM architecture image for `guacd`, the RDP feature has been disabled, and the related image will no longer be pulled for the time being.

+5. For data backup, please back up the **data** folder in the directory yourself. This project does not provide any backup functionality.
