I never saw the point in Diataxis, but honestly while vibe coding it's pretty convenient to tell an LLM "do diataxis" and get decent first pass documentation out of it.

I urge people to not read this. Once you do, you will see all documentation will as the flawed and confusing mess it is. Ignorance is bliss!

Perhaps add "A systematic approach to technical documentation authoring" to the title?
