Where best to begin with Unity (Quest)?

Hello,

I am an experienced coder in C#, a beginner-to-intermediate gamemaker with Unity, but I am totally new to XR. I really like the Oculus Integration package but implementing something as simple as movement is a challenge. The best asset to start with seems to be the PlayerController from the Locomotion sample framework, but it has way more functionality than necessary and way more scripts and it's tough to figure out how to get it to work with only teleportation, which is what I want. (on my Quest 2, teleportation isn't even working in the Locomotion scene itself for some reason.)

The documentation is good with what it discusses, but is totally insufficient when it comes to the real nuts and bolts of making and modifying these objects and scripts. YouTube videos almost all use old versions of Oculus Integration (currently it is version 23.1) so I can't do what they are doing, I need help with Oculus Integration 23.1.

So without good documentation and good tutorials elsewhere, I am lost. Where do I start if I want to learn???

Thanks!
