 Django
 ~~~~~~
 
-Even without a Django backend, you can use MongoDB and {+driver-short+} with most of
-what Django provides. Certain features of Django that require
-``django.db``, such as admin, authentication, and sessions, will not work
-when using only MongoDB.
-
-- `Django MongoDB Engine <https://django-mongodb-engine.readthedocs.io/en/latest/>`__
-  is a MongoDB database backend for Django that
-  supports Django aggregations, atomic updates, embedded objects, Map/Reduce, and GridFS.
-  It allows you to use most of Django's built-in features, including the ORM, admin,
-  authentication, site and session frameworks, and caching. For more information, see the
-  `Django MongoDB Engine tutorial <https://django-mongodb-engine.readthedocs.io/en/latest/tutorial.html>`__.
-
-- `Django MongoEngine <https://github.com/MongoEngine/django-mongoengine>`__ is a
-  MongoDB backend for
-  Django. The repository also includes an `example application <https://github.com/MongoEngine/django-mongoengine/tree/master/example/tumblelog>`__.
-  For more information, see the `Django MongoEngine documentation <https://django-mongoengine.readthedocs.io/en/latest/>`__.
-
-- `Djongo <https://www.djongomapper.com/>`__ is a connector for using
-  Django with MongoDB as the database backend. With Djongo, you can use the Django Admin
-  GUI to add and modify documents in MongoDB.
-  The `Djongo source code <https://github.com/doableware/djongo>`__ is hosted on GitHub,
-  and the `Djongo package <https://pypi.python.org/pypi/djongo>`__ is on PyPI.
-
-- `mango <http://github.com/vpulim/mango>`__ provides MongoDB backends for
-  Django sessions and authentication (bypassing ``django.db`` entirely).
+You can use the official `{+django-odm+} <{+django-docs+}>`__
+to use MongoDB as your database in Django applications. {+django-odm+}
+is a Django database backend that uses PyMongo to connect to
+MongoDB. By using the backend, you can use Django models to represent
+MongoDB documents, with support for Django forms, validations, and
+authentication. {+django-odm+} also enables you to use
+MongoDB-specific querying optimizations in your applications, such as
+aggregation operations and indexes.
+
+.. important:: Public Preview
+
+   {+django-odm+} is in Public Preview and intended for evaluation purposes only.
+   Public Preview is not recommended for production deployments, as breaking changes
+   may be introduced.
