Recap + practice

Your six commands

git init — start the time machine
git status — where is everything? (when lost → status)
git add — stage the shot
git commit -m "why" — take the snapshot
git log — read the diary
git checkout <id> / git switch - — time travel

Homework — 5 minutes

Make one more repo from scratch — a recipe collection, a journal, anything.
Do three commits with honest messages.
Read your own git log and feel smug.

practice terminal — you cannot break it

Questions people always ask

“I committed something wrong!”

You never rewrite the past on Day 1 — just fix the file and commit again. History is append-only for now; undo commands exist and get their own lesson later.

“Where is all this stored?”

100% on your laptop, inside .git. No cloud, no account, no internet — until Day 3.

“Why the terminal instead of VS Code buttons?”

The buttons run these exact commands underneath. Learn the commands once → every GUI in every tool makes sense forever.

Tomorrow

Day 2: parallel universes 🌿 — branching, merging, and surviving your first merge conflict. See you there.
