+edX Extensions
+==============
+edX.org has its own app, ``edx_catalog_extensions``, to contain edX-specific customizations. These include data
+migrations, management commands, etc. specific to edX. Non-edX users should NOT use this app. This app
+is explicitly disabled by default in all non-test environments.
+
+At some point in the future this app will be moved to a separate repository to avoid confusion. It exists here now
+until we can determine what other edX-specific components need to be extracted from the general project.
+
+edX developers should add ``'course_discovery.apps.edx_catalog_extensions'`` to the ``INSTALLED_APPS`` setting in a
+``private.py`` settings file.
