 In this more complex example we assume that the ``News`` and ``Image`` models
 are registered in ``translation.py``. The ``News`` model has an own custom

+Using a Custom jQuery Library
+-----------------------------
+
+If you don't want to use the jquery library shipped with Django, you can also
+include a standard one. While this adds some redundancy it could be useful in
+situations where you need certain features from a newer version of jquery
+that is not yet included in Django or you rely on a non-namespaced version of
+jquery somewhere in your custom admin frontend code or included plugins.
+
+In this case you don't need the ``force_jquery.js`` static provided by
+modeltranslation but include the standard jquery library before jquery-ui like
+this:
+
+.. code-block:: python
+
+    class NewsAdmin(TranslationAdmin):
+        class Media:
+            js = (
+                'http://code.jquery.com/jquery-1.8.2.min.js',
+                'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.24/jquery-ui.min.js',
