OK, I finally found how to do.
Chris, the existing documentation is very detailled, obviously, but some things may be added, I think, like examples for use of each function (look how it's made on cplusplus.com, to have an idea).
Furthermore, a tutorial may as well be very useful, 'cause some users don't know the whole API content. Eventually, I'll try to do something for the tutorials on the website when I'll be able to.
