Document add-ins that must be installed to run test and write a sample Unit test on a function to prove functionality. Assume a contributor has No Idea how to create a test and run it.

Use the ExsampleCommand and ExsampleSubsystem to demonstrate Unit Test.

How should we branch if multiple users are attempting to resolve? Should each user create a branch as FRC4607:BSOS:"User_Feature_Branch" or fork to personal repo then pull request from there?

The first option could result in a lot of orphaned branches connected to the Main Repo where the latter would be orphaned on your personal fork.
