When a user ends up in a "detached head" state, this is a scary situation, but as we know, Git is not scary.

1. Run source setup.sh (or .\setup.ps1 in PowerShell)

1. Run git status and git log --oneline --graph --all to see what is going on.
2. Restore normalcy in this repository by moving to master

Note that this task might seem more confusing if you did not run setup.sh in your terminal.

We want to have a branch called the-beginning that is made from the first commit with message A.

3. Can you do this by first causing a detached head?

• git status
• git log --oneline --graph --all
• git checkout <ref> or git switch --detach <ref>
