+#!/usr/bin/env python3
+"""A script that:
+
+- Optionally restores data from a json file.
+
+- By default, without any args provided, adds the group: 'editors' to
+every resource. 'editors' should have the right to edit both metadata
+and data.
+
+- Optionally creates a back-up every time you edit a resource.
+
+
+To restore a back-up:
+
+.. code-block:: python
+   python resource.py --restore <PATH/TO/RESOURCE/BACK-UP/FILE>
+
+To add editors to every resource without creating a back-up:
+
+.. code-block:: python
+   python resource.py
+
+To add editors to every resource while creating a back-up before any
+destructive edits:
+
+.. code-block:: python
+   python resource.py --enable-backup
