Git repository

the .git directory serves as the git repository

In Git terminology, the git repository is the .git directory managed by git. It is a hidden directory that lives at the root of the project. It stores all versioning data.

Because the directory stores all the project's data, we sometimes conflate it with the project directory itself, the one that lives locally and that contains both the working tree and the git repository proper.

The git init command creates the .git repository and enables git commands.
