The goal of this tutorial is to introduce two fundamental pieces of
git's architecture--the object database and the index file--and to

-a", which creates a commit including every change you've made to
your working tree. But what if you want to commit changes only to
certain files? Or only certain changes to certain files?

The thing that it's comparing against is actually the index file,
which is stored in .git/index in a binary format, but whose contents
we can examine with ls-files:

the index with all changes in the working tree.

In addition to being the staging area for new commits, the index file
is also populated from the object database when checking out a
branch, and is used to hold the trees involved in a merge operation.
