Welcome to Part 2: Basic Repo Usage: Committing and History!
The second installment of Source Control: The Good Stuff.

This video demonstrates the basic process of making design changes and committing those changes into your Mercurial repo. After that we take a look at how to use the history stored within your repo so you can "go back in time to a better place" when maybe your code worked, uh, better.
