+
+## About
+
+The documentation is in four parts for the frontend, the backend API, the controller code, and how 
+the previous three parts work together.
+This is because they are fairly segmented and were separate projects worked on by different people.
+Jacob Priddy wrote the initial backend API and controller projects while Jarod Owen wrote the initial
+web frontend.
