+Dashboard for weight-based shipping methods
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There is a new dashboard for weight-based shipping methods. It isn't enabled by
+default as weight-based shipping methods are enabled by default. To add it to
+the dashboard menu, include this snippet in your ``OSCAR_DASHBOARD_NAVIGATION``
+setting:
+
+.. code-block:: python
+
+    OSCAR_DASHBOARD_NAVIGATION = [
+        ...
+        {
+            'label': _('Shipping charges'),
+            'url_name': 'dashboard:shipping-method-list',
+        },
+        ...
+    ]
+
+You'll also need to modify your shipping repository class to return weight-based
+shipping methods too.
