[description]
But Git allows to you capture changes with more precision!

To understand how to do that, you need to learn about [your teacher raises her voice dramatically] *the index*!
In the index, we can prepare what will be in the next commit. In this game, the index is represented by a blue aura!
Initially, all files are untracked. If you have a file, and you want to have it in the next commit, use `git add`!
Here, we don't use the fancy commit card, but a plain `git commit`!
