Not sure what you mean by "tutorial" but there is a lot of information on this forum about binding in general.
This Thread I Wrote
goes over almost all binding methods available that includes pictures of someone who is over a D-cup binding to a "flat" chest and there are other pictures throughout as well.
Cup size doesn't matter in binding, measurements do when picking out a binder and anatomy can restrict you from wearing some of the "lighter" binders if your breasts do not compress easily.
A real "D" cup is rather small, so it shouldn't be too hard to bind. If you think you have enough tissue for it to be difficult to bind you might be larger than a D cup - since many people are wearing the wrong bra size. There is a post here
that I wrote for unrelated reasons that covers that subject. I know that's an awkward thing to say but it's my pet cause because a bra that fits can really change your life.
