Website should document your journey through MSD, so include work-in-progress as well as latest results. Use pdf's for display whenever possible so that information is easily viewable without the need to download files and open applications. (Your EDGE file repository should still contain original files).

Sample categories are listed below, but feel free to change or add nodes to better correspond to your project and your Guide’s expectations.
