Repository
A project folder being tracked by Git. Shortened to "repo."
A repository is any folder Git is tracking. It holds your project files plus a hidden .git directory with the full history.
You create one with git init inside a new folder, or clone someone else's with git clone <url>. Every repo has its own independent history.
Shorthand is repo. "Push to the repo." "Clone this repo." "The Mosaic repo." Same thing — the project folder under Git's control.
