+Route on shipping method
+------------------------
+
+Optionally, set different warehouse delivery processes for a shipping method by configuring
+different :doc:`routes <daily_operations/use_routes>` for it.
+
+.. example::
+   Configuring multiple routes per shipping method is helpful for adjusting warehouse delivery
+   processes based on:
+
+   - speed (e.g., use :doc:`one-step delivery <daily_operations/receipts_delivery_one_step>` for
+     express shipping, or :doc:`two-step <daily_operations/receipts_delivery_two_steps>` for
+     standard shipping).
+   - international shipping (e.g. use :doc:`three-step delivery
+     <daily_operations/delivery_three_steps>` to prepare documents for customs)
+   - in-store pickup or home delivery: ship from the central warehouse, or pick from the store's
+     stock, depending on customer selection.
+
+To set up routes, go to :menuselection:`Inventory app --> Configuration --> Routes`. Click
+:guilabel:`New`, or select the desired route.
+
+On the route form, in the :guilabel:`Applicable On` section, tick the :guilabel:`Shipping Methods`
