Repository

Not the same as a folder

A folder holds the current files. A repository holds their whole history too, in a hidden `.git` directory — which is why copying a project without it loses everything except this moment.

Where it bites

A repository remembers what you committed even after you delete it. A secret committed once and removed in the next commit is still in the history, and pushing that history publishes it.
