Now that we have initialized our mastering folder to be a local repository, we can add the contents of the folder to Git for tracking any changes. Adding and committing files requires two steps.

The first is adding the entire contents of the folder or specific files. In our example, we can add the entire Drupal instance by typing the following command in the Terminal window:

git add. 

Second, we need to tell Git what we have added by committing the files and including a message describing what the addition contains. This can be accomplished by entering the following command in the Terminal window:

git commit -m 'Initial Drupal instance added to repo'
