For games, just use your package manager to install Steam, then install Proton from there. (IIRC it's automatic for just the standard release version.) Steam games should mostly just work without you needing to do anything. Other games, you want to use something like Heroic or Lutris (I recommend the former) to manage them and launch them with Proton without manually doing it all every time.

If you expand on what your issues were, I'm sure plenty of people would be happy to help. Again, it should be pretty trivial, so I'm not sure what went wrong.
