Everything on VR and Facebooks meta verse

I'm looking for someone who is willing to build a tutorial on Facebooks Metaverse, VR, AR, and how to write code to integrate with the meta verse and other VR applications. This is meant to be at a high level overview. At the end, I should understand exactly what it is, How to invest into it, How I can use AR/VR to craft something similar and whats next.
