I don't know how to use [library X]. Is there any document (besides [the library X API documentation * ]) about using [library X]?
Perhaps it's just me being stodgy, but I would say the answer is,
No. The answer is such a forceful no that, personally, I would not bother answering, because a message consisting entirely of,
No, there isn't, isn't very helpful, although it's the absolute truth, and any attempt at a longer, helpful message would become a longer, hurtful message.
( * For reference, the API is the documentation that tells one how to use a library.)
