What you describe sounds a lot like Diátaxis[1], which is a strategy for writing and organizing technical documentation. It categorizes docs into one of four categories: tutorials, explanations, how-tos, and references.

Category is derived from a fairly simple heuristic: whether the content informs action or cognition, and whether the content serves the reader’s application or acquisition of a skill[2]. I’m a fan and it’s simple enough that most anyone can learn it in an afternoon.
