// hands-on lab

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:

1. `git status` — observe the "not a git repository" error (you'll see it often in life) 2. `git init` — create the repo 3. `touch runbook.md` then `git add runbook.md` 4. `git status` — read it: the file is STAGED ("to be committed") 5. `git commit -m "add runbook skeleton"` 6. `git log` — your snapshot exists, with hash and message 7. Bonus: `git add .` stages everything; try another commit.

// checklist

git init creates the repository
git add stages a file (git status shows it)
git commit -m records a snapshot
git log shows your commit with its hash
