+Course Permutation Tool for Developer Environments
+########################
+
+This is a tool to add default courses to developer environments, specifically for
+devstack and sandboxes. The goal is for developers to have access to courses with
+metadata that matches that in production, and to provide a way to generate course
+permutations. It will be comprised of a permutations JSON file, which
+includes permutation options and default values, and also a Python script that will
+generate the final file that will get passed into a course creation script.
