+django-admin-rangefilter
+------------------------
+
+In order to fix compatibility issues with ``django-admin-rangefilter`` package you should use JET's admin filter class
+``jet.filters.DateRangeFilter`` instead of ``rangefilter.filter.DateRangeFilter``.
+
+.. code:: python
+
+    #from rangefilter.filter import DateRangeFilter
+    from jet.filters import DateRangeFilter
+
+
+    class MyUserAdmin(UserAdmin):
+        ...
+        list_filter = (
+            ('date_joined', DateRangeFilter),
+        )
