Oh man, I FEEL this comment. That was one absurdly awful set of documentation, because they not just have a lot of confusingly placed repeat content, they also follow the philosophy of only explaining top level initial conceptual primer for everything, and only explaining the actual main use case of the component 3 navigation pages deep.
So a beginner has to jump a BUNCH of pages to get a primer, and an expert has to bookmark the couple actually-useful pages and later give up and just look at github for specific operators/processors when they already know the basic config inside out.
