Repository

In practice, a repository is any folder
we told git to version control

Repository

From terminal, we move into the folder
which we want to version and...

git init

Initialized empty Git repository in /path/project/.git/

We created our first repository

Command init makes the current directory a git repository

n.b. it is not required for the directory to be empty
