How to read recommendations in learning guides

A learning guide should explain the audience, task, accessibility considerations, and limitations behind a recommendation. Calling something beginner-friendly is not enough on its own. I'm interested in which explanations help readers judge whether a recommendation fits their own needs.

I need to know what a guide assumes I already understand. A short prerequisites note would help me decide where to start.

I'd prefer an explanation of the tradeoffs over a best-for-everyone label.
