Each currently existing module has an overview section that is very helpful, see Module Overviews: Introducing 3 modules to learn about Deliver, Describe and Manage, and Select and Acquire.
OLE Video Tutorials

Getting Under the Hood
OLE, like all Kuali products, has a lot of tables, and the Maintenance UI is where all the tables can be populated.
The spreadsheet at this link: https://docs.google.com/a/kuali.org/spreadsheets/d/1U5knuOE2cNuJMSYLHz3X_O2OKknSLE7iKl4A-Ylui6s/edit#gid=934970656 lists every link on the maintenance UI, its associated table name, and links to workbooks where the tables are further explained and examples are shown.
