This page contains links to all the information a developer should need to get started developing tools and apps for Sakai. This is meant to be a kind of Sakai development walkthrough. It contains a section on where to get more information and then links to get you on the path from regular a Java programmer to Sakai superstar (or something like that). If anything is missing or confusing please contact Aaron Zeckoski.
