Building and Fitting Drawers

Good morning. Thanks to this site, I have finally found a new favorite hobby and have now built many different pieces of furniture for our home. However, I have never built a piece that needed a drawer.....until now. I am going to being building a modified version of the Extra Long Buffet Cabinet (http://ana-white.com/2015/02/free_plans/extra-long-buffet-cabinet) and I want to include 1 drawer.

Since I have never built or fitted a drawer into a piece before, I am a bit apprehensive. When building the drawer, how much room on the sides do I allow for the drawer slides? Is that determined by the size of the drawer slides?

Does anyone have a link to an article, or video, on general techniques for building and fitting drawers? Any advice would be extremely appreciated.

Also, this may be a great topic for a video post, Ana...hint, hint.

Thanks in advance!
