First repository

~12 min

Init, stage, commit and read history in the practice shell.

The in-page shell has a working git. Drill the core loop:

git status — observe the "not a git repository" error (you'll see it often in life)
git init — create the repo
touch runbook.md then git add runbook.md
git status — read it: the file is STAGED ("to be committed")
git commit -m "add runbook skeleton"
git log — your snapshot exists, with hash and message
Bonus: git add . stages everything; try another commit.
