Why do the Linux instructions look so complicated? Why search for "cmd" when terminal (or pressing [Alt]+[t] would be faster? In the file explorer/manager there is usually a - right click - run from/in terminal option. you could do it straight from the folder.
All of this would be unnecessary if the .sh was made executable before compressing. And don't use .zip - use something more advanced like .tar.
Linux is usually easy to use(ZorrinOS, FerenOS, Elementry). This makes me feel uncomfortable like a teenage gamer trying to show their oblivious parent how to use a controller.
