Hot take: RTFM means *read the fucking manual*, and "manual" is singular, not plural.

If someone's asking for the documentation for X, and the only thing available is guides, linking to other guides, which have services, which you then need to read man pages for, then the correct response is 'no, there is no documentation - everyone just reads all the guides to all the parts'.

The correct answer is not "RTFM", because there is no manual.
