If you're looking for a "how to" tutorial, you might find this Ison's video helpful. In my opinion, it is an excellent video.
This diagram from the Alabama Extension Service shows a little more clearly what is meant by pruning it back to "2 buds." The extension service is saying 2 to 3 and Ison's says 1 to 2. I think most of my cuts were to 3 buds.

I'm looking forward to this in the fall.
I may have to try a pie or something this year if I get a decent crop. I came across a muscadine dreamcake recipe at a nursery this past year. The pie looks divine, but I would probably alter it, using ingredients more readily available to me.
If you are deliberating about getting a muscadine, I highly recommend taking the plunge.
