more git commands (2)

10. Adding All Changes
You also can use wildcards if you want to add many files of the same type. Suppose that I've added a bunch of .txt files into
your directory.I put some in a directory named "octofamily" and some others ended up in the root of our "octobox" directory.
Luckily, we can add all the new files using a wildcard with git add. Don't forget the quotes!
git add '*.txt'
