+"""A script for adding users to a specific group.
+
+Example:
+
+Assuming there are no groups and 'test@bonfacemunyoki.com' does not
+exist in Redis:
+
+.. code-block:: bash
+   python group.py -g "editors" -m "test@bonfacemunyoki.com"
+
+results in::
+
+   Successfully created the group: 'editors'
+   Data: '{"admins": [], "members": []}'
+
+If 'me@bonfacemunyoki.com' exists in 'users' in Redis and we run:
+
+.. code-block:: bash
+   python group.py -g "editors" -m "me@bonfacemunyoki.com"
+
+now results in::
+
+   No new group was created.
+   Updated Data: {'admins': [], 'members': ['me@bonfacemunyoki.com']}
