There is a real problem there, and that page doesn't do a good enough job of dealing with it. I have something cooking that is much, much better.
The docs I have built up are at times too technical for users and not detailed enough for developers. I am not sure if it's a skill issue on my part for an individual piece of text, a skill issue on my part in applying the principles outlined by Diataxis, or a fault in the framework itself (or its self-documentation).
