 ## Controller Node and Computer Node Installation
 
+- Supported Systems: Debian10+, Ubuntu18.04+
+- Recommended system: Debian12+, Ubuntu22.04+.
+- Lower versions of the system will automatically compile the new version of python installation package before deployment, so it is recommended to use a new system without compiling directly installed!
