Add Documentation section that exposes Engine Architecture
version: 3.4.3
Issue description: There's no documentation about how the engine works.
Some map (using diagrams) of the engine layout/architecture; rendering pipeline, engine-server co-relation, etc. Also how the type-system relates to, and essential stuff that anyone should know (there's info out there, but it looks spread and hidden).
Just in case, there exists already something like that?
This documentation already exists: https://docs.godotengine.org/en/stable/development/cpp/index.html
Please be more specific if you need documentation on a subject that isn't already covered.
The rendering pipeline is likely the main aspect that isn't covered in the documentation. There's been a few blog posts about it back in 2019-2020, but these are slightly outdated by now. Knowing how the rendering pipeline works isn't important for most people, but it's useful if you intend to write your own rendering backend. I think having documentation for things like https://github.com/godotengine/godot-docs/issues/4834 first is more important, still.
The audio and physics engines could also use internal documentation, but reduz is planning to create a video about how GodotPhysics works (no ETA).
