First, these scripts need to be executed under SSH, as there is no graphical interface (LuCI). Installation is relatively simple and convenient to use. Of course, you can use third-party SSH tools to connect, such as Termius or Finalshell, or the TTYD WebShell that comes with the router system.
It is important to note that all scripts are located in /usr/bin.
