 .. index:: Jython, Java, JVM
 
-As of January 2014, the latest release of `django-jython`_ supports Django 1.3
-which is no longer supported (receiving fixes or security updates) by the
-Django Project. We therefore recommend that you do not try to run Django on
-Jython at this time.
+Jython_ is an implementation of Python that runs on the Java platform (JVM).
+This document will get you up and running with Django on top of Jython.
 
-The django-jython project is `seeking contributors`_ to help update its code for
-newer versions of Django. You can select an older version of this documentation
-to see the instructions we had for using Django with Jython. If django-jython
-is updated and please `file a ticket`_ and we'll be happy to update our
-documentation accordingly.
+Installing Jython
+=================
+
+Django works with Jython versions 2.7b2 and higher. See the Jython_ Web site for
+download and installation instructions.
+
+.. _jython: http://www.jython.org/
+
+Creating a servlet container
+============================
+
+If you just want to experiment with Django, skip ahead to the next section;
+Django includes a lightweight Web server you can use for testing, so you won't
+need to set up anything else until you're ready to deploy Django in production.
+
+If you want to use Django on a production site, use a Java servlet container,
+such as `Apache Tomcat`_. Full JavaEE applications servers such as `GlassFish`_
+or `JBoss`_ are also OK, if you need the extra features they include.
+
+.. _`Apache Tomcat`: http://tomcat.apache.org/
+.. _GlassFish: https://glassfish.java.net/
+.. _JBoss: http://www.jboss.org/
+
+Installing Django
+=================
+
+The next step is to install Django itself. This is exactly the same as
+installing Django on standard Python, so see
+:ref:`removing-old-versions-of-django` and :ref:`install-django-code` for
+instructions.
+
+Installing Jython platform support libraries
+============================================
+
+The `django-jython`_ project contains database backends and management commands
+for Django/Jython development. Note that the builtin Django backends won't work
+on top of Jython.

-.. _`file a ticket`: https://code.djangoproject.com/newticket
+
+To install it, follow the `installation instructions`_ detailed on the project
+Web site. Also, read the `database backends`_ documentation there.

+
+Differences with Django on Jython
+=================================
+
+.. index:: JYTHONPATH
+
+At this point, Django on Jython should behave nearly identically to Django
+running on standard Python. However, are a few differences to keep in mind:
+
+* Remember to use the ``jython`` command instead of ``python``. The
+  documentation uses ``python`` for consistency, but if you're using Jython
+  you'll want to mentally replace ``python`` with ``jython`` every time it
+  occurs.
+
+* Similarly, you'll need to use the ``JYTHONPATH`` environment variable
+  instead of ``PYTHONPATH``.
+
+* Any part of Django that requires `Pillow`_ will not work.
