We assume you have complete comfort with the concepts introduced in "Getting Started" and "Basic." Concepts like making a repo, cloning it, pulling changes, making commits, and pushing changes should be second nature to you. You shouldn't have any issue looking up a commit history or reverting your code. For people with a very deep familiarity with Git or who already have a hosted solution, we also have a section on how to migrate your existing repositories to Copia.
