Steam

Install

So steam was more of an issue because it wasn't showing at first in the app but if you go in discovery and then in settings you will find all the repositories you can download from and some of them are unchecked ( you need to have selected the fact you can use third party repositories during the installation process of Fedora KDE otherwise you might not see this option )

I checked everything that's steam related and also the main rpm Fusion non free otherwise some packages might not download (you probably don't need steam debug and steam source but I'm new to this too :P)

After that you just need to search steam and you should be able to find it now.
