Concept

• Git fundamentals - Git’s four places, the everyday commands that move work between them, the commit workflow, and keeping secrets out.

Playbook

• Branches and pull requests - Keeping a branch in sync with its upstream and taking it through the GitHub pull request workflow.
• Undoing and recovering in Git - Choose between restore, reset, revert, and reflog by whether the work is shared, and check a pre-flight list before any destructive Git operation.
