You should not need more than that, but I am pretty sure that if you need more you will find more, even on this forum. I think that card is one of the best documented, there are several versions of the same card, so any document showing a similar card will also fit your card. Just find the right current setting for your motor, set the micro stepping and that's it. Very simple, really.
