I would check out the book "The Darkroom Cookbook" by Steve Anchell (and by "check out," I also mean that it may be available at a library near you). There are five useful paragraphs on stand development that will do more for you than piecing together tidbits from the Internet as your first introduction to the technique. One paragraph is introductory, one is on advantages, one is on disadvantages, and two that explain the basics of how to employ the technique.
