There really isn't a one-size fits all instruction manual...I'd suggest taking a couple classes, reading a few books, and above all, keep an open mind and a keen eye to see how the baby is doing, to tell whether you're doing it "right" or not.
As long as the baby is generally happy, healthy, and progressing to the best of his/her ability...you're doing fine. But keep trying new things, or old things a second time, in order to get better at it.
Good luck!!
