Recap - Detective Work

The folder contains users.txt with two lines.

Every run starts from a fresh copy of the folder, and the whole script in the editor runs again from the top. Nothing is committed for you: begin with git init -q -b main, set git config user.name and git config user.email, and commit the starting file. Keep those lines in the editor. If you clear them you will see fatal: not a git repository.

Make this change and review it:

1. Append the line charlie to users.txt (do not stage or commit it).
2. Run git diff to display the unstaged change.
