Hello!
This repository is a training area for Git activities.
To work in this repo, you'll need to fork it. In GitHub, there's a button for that in the upper right corner of the repo's main page. Forking creates a copy of the repo that you own, and are allowed to make changes to -- you can't work on it otherwise. I've set this original repo so that only I can change it, so you won't be able to work on it directly.
