So, I have the Pro, and Q3. I have only been using them natively with games available in the Meta store. I see all of these people talking about UEVR and PCVR, and I think I would like to take the dive and try them out. I have never used Steam, I honestly don't really know what it is (Yes, I am old). So all of that leads to the title of my post. Is there a step-by-step guide for setting those up? I have an Alienware M15 R4, which I believe is capable. I do not have any other equipment, other than a link cable.

Also, am I seeing that I can play my XBOX games on my quest? How does that happen if they are physical discs, not digital downloads?

Thank you in advance for your help!
