Can someone please explain to me how to install on linux because i do not use linux often and normally have no clue what I'm doing. Any help is very appreciated.

idk what desktop environment you are using but you need to unzip the file yourself

then go into a terminal and type chmod +x ./Downloads/<unizpped folder>/robes-beta-5-linux.x86_64

now you can just launch it from your file explorer by double clicking it or run from terminal with ./robes-beta-5-linux.x86_64
