+Reversing Admin URLs
+====================
+
+.. versionadded :: 1.1
+    Before Django 1.1 it wasn't possible to reverse admin URLs.  In addition 
+    for this to work you need to be using the new Django 1.1 ``include()`` 
+    syntax for setting up admin URLs.
+
+The following are the url names, and parameters for ``AdminSite`` urls, all 
+url names are prefixed with the ``AdminSite`` instace's name, followed by an 
+underscore, so if an ``AdminSite`` was named ``"user_admin"`` it's urls names 
+would be prefixed with ``"user_admin_"``, the default ``AdminSite``'s name is 
+``''`` however it's names *do not* have the trailing underscore:
+
+    ======================  =============================== =============
+    Page                    URL name                        Parameters
+    ======================  =============================== =============
+    Index                   ``admin_index``
+    Logout                  ``admin_logout``
+    Password change         ``admin_password_change``
+    Password change done    ``admin_password_change_done``
+    i18n javascript         ``admin_jsi18n``
+    Application index page  ``admin_app_list``              ``app_label``
+    ======================  =============================== =============
+
+The remaining urls are for ``ModelAdmin`` instances, these too are all prefixed 
+with the ``AdminSite``'s name(with the same caviets as the ``Adminsite``, and 
+``app_label`` and ``model_name`` are the lowercase versions of the 
+application's name and the model's name:
+
+    ======================  =====================================================   =============
+    Page                    URL name                                                Parameters

+    Changelist              ``admin_{{ app_label }}_{{ model_name }}_changelist``
+    Add                     ``admin_{{ app_label }}_{{ model_name }}_add``
+    History                 ``admin_{{ app_label }}_{{ model_name }}_history``      ``object_id``
