+Disabling Functionality
+///////////////////////
+
+``configure()`` also accepts keyword arguments that can be passed ``False`` as a value, which will disable automatic configuration for their specific areas of responsibility:
+
+- ``databases``
+- ``test_runner``
+- ``staticfiles``
+- ``allowed_hosts``
+- ``logging``
+- ``secret_key``
+
+-----------------------
+
+You can also just use this library to provide a test runner for your Django application, for use on Heroku CI::
+
+    import django_heroku
+    TEST_RUNNER = 'django_heroku.HerokuDiscoverRunner'
