Repository
aka: repoaka: git repo
The Quick Version
The tracked home of your project's code and its full history.
How it actually works
A repository is a folder that Git watches. It stores every version of every file you have committed, plus branches and messages describing what changed. A remote repository (on GitHub, for instance) is a copy hosted online.
Why does it matter?
It is your undo history, your backup, and the thing hosting platforms read to deploy your site.
Example
github.com/yourname/landscape-pro is a remote repository.
