It goes through everything in great detail & without suggesting you need to buy all sorts of expensive binding tools in order to accomplish a beautiful binding. If you have an acrylic ruler, a pair of scissors & a threaded needle, you can make a beautiful mitered binding with this tutorial.
If you'd prefer to do the whole thing by machine, rather than hand-finishing the binding, Quilty has a good video on how to start:

Sewing with Nancy shows how to machine finish (unfortunately, while plugging a bunch of the tools she sells). Skip to minute 5:30 to just get the info about machine stitching down the binding to finish it off.
