Branch workflow

~12 min

Practice branch → commit → switch back, end to end.

Continue in the shell (git init first if you're in a fresh session):

git init && touch config.yaml && git add . && git commit -m "base config"
Create a work branch: git checkout -b tune-limits
git branch — the * marks where you are
Make a change: echo "cpu: 500m" >> config.yaml then git add . && git commit -m "raise cpu limit"
git log — see both commits on this branch
Return home: git checkout main
