Documentation for RMFU

AS RMFU, I NEED to know the details of how to use the system and how it is constructed and works (architecture), SO THAT we can install, maintain and extend, if necessary.
AS AN RMFI ADMINISTRATOR, I NEED to know how the Administration pages work, SO I can administer effectively.
AS CODE FOR DENVER, I NEED a record of the RMFU project, SO THAT I can use it for demonstration of successful projects.
