This sounds as if you are adding new functions to the header file.
Saying "... to the api docs" would been clearer. Better:
config: document new query functions

One might expect these functions to be documented in the same patch
which introduces them. Since this patch is so small, it might make
sense just to squash it into patch 1.

Minor observation: As this file is documenting the API, mentioning
private implementation details such, as the "internal cache", may be
frowned upon (though probably doesn't matter in practice since this
_is_ a technical document).
