As another commenter suggested I think a really solid foundation in ECS architecture will get you some of the way, but you're totally right that the documentation is sparse. I think the engine should really be thought of as being in alpha right now given how rapidly it's evolving and how unstable different APIs are. I suspect at some point the docs would stabilize. IMO you should only really bother with Bevy right now if you find it inherently interesting and you are down to dip into the source sometimes. Even in the universe of Rust based ECS game engines there are more stable and documented options.
