There are a bunch of good tutorials out there. I don't remember which one I followed so I can't recommend anyone specific.

I used ALVR and found it quite easy to get setup with + its FOSS which I prefer

https://github.com/JackD83/ALVR is the fork to use, its instructions arent super indepth but I got there its not too hard. And then steam views it like a regular steam vr headset. Its pretty cool.
