+=====================
+Planning an itinerary
+=====================
+
+By default, **Odoo Field Service** shows a static map where all task locations for the day are
+pinned. To make it more useful for the field service workers, it is possible to display an itinerary
+on the map using MapBox. To do so, enable the **Map Routes** feature as follows:
+
+#. Create or sign in to a MapBox account using the following link: `<https://www.mapbox.com/>`_.
+#. `Create a token <https://docs.mapbox.com/help/getting-started/access-tokens/#adding-url-restrictions-to-access-tokens>`_.
+#. Go to the `Access tokens page on Mapbox <https://account.mapbox.com/access-tokens/>`_ and copy
+   your token.
+#. In Odoo, go to the :guilabel:`Settings` app and scroll down to the :guilabel:`Integrations`
+   section. Paste your Mapbox access token in the :guilabel:`Token` field under
+   :guilabel:`Map Routes`, and click :guilabel:`Save`.
+
+Displaying your itinerary on a map
+==================================
+
+.. important::
+   For a field service task to be featured on the map, it needs:
+
+   - a :guilabel:`Planned Date`;
+   - a valid address linked to the customer’s profile.
+
+To display your tasks on a map, go to :menuselection:`Field Service --> My Tasks --> Map`. To create
+your itinerary, Odoo sorts out your field service tasks based on their :guilabel:`Planned Date` to
+show the way from one location to the next.
+
+To open your itinerary on the Google Maps website or app, click :guilabel:`View in Google Maps`.
+Google Maps includes your current location as a starting point for your itinerary.
+
+.. tip::
+   - By default, the map shows today’s tasks. Remove the :guilabel:`Today` filter in the search bar
+     to display all tasks. Your tasks are then sorted by date in the left column.
+   - Click your task in the left column or the map pin to display the task's details. From there,
+     you can :guilabel:`Open` the task or click :guilabel:`Navigate to` to get an itinerary from
+     your current location to this specific task's location.
