+The `print_commit` function takes in a GitPython commit object and
+prints the 40-character SHA-1 hash for the commit followed by:
 
+1. the commit summary
+1. author name 
+1. author email
+1. commit date and time
+1. count and update size

+Below the `print_commit` function, create another function named 
+`print_repository` to print details of the `Repo` object:
 
 ```python
 def print_repository(repo):
-    print('Repo active branch is {}'.format(repo.active_branch))
     print('Repo description: {}'.format(repo.description))
     print('Repo active branch is {}'.format(repo.active_branch))
     for remote in repo.remotes:
         print('Remote named "{}" with URL "{}"'.format(remote, remote.url))
     print('Last commit for repo is {}.'.format(str(repo.head.commit.hexsha)))

 ```
 
+`print_repository` is similar to `print_commit` but instead prints the
+repository description, active branch, all remote Git URLs configured

+The main function handles grabbing the `GIT_REPO_PATH` environment variable
+and creates a Repo object based on the path if possible.
 
+If the repository is not empty, which indicates a failure to find the
