Git, Just Enough to Follow Along
Git is how the course moves a project onto your machine and keeps a record of what changed. It's free, and this guide covers only the small part of it the course uses.
Do you already have this?
Git has a reputation it partly deserves, but you won't need branching, merging, or rebasing. You'll need it installed, with your name and email set, because git won't record a change until it knows who you are.
To check, open a terminal and run the commands below.
git --version
git config --global user.name
