+How to setup a delivery method? 
+===============================
+
+Overview
+========
+
+Odoo can handle various delivery methods, but it is not activated by
+default. Delivery methods can be used for your sale orders, your
+deliveries but also on your e-commerce.
+
+Delivery methods allow you to manage the transport company, the price
+and the destination. You can even integrate Odoo with external shippers
+to compute the real price and the packagings.
+
+Configuration
+=============
+
+Install the inventory module
+----------------------------
+
+Delivery methods are handled by the **Delivery costs** module. Go to
+**Apps** and search for the module. You should remove the **Apps** filter in
+order to see it :

+   :align: center
+
+.. note::
+    If you want to integrate delivery methods in your e-commerce,
+    you'll have to install the **eCommerce Delivery** module.
+
+Configure the delivery method
+-----------------------------
+
+To configure your delivery methods, go to the **Inventory** module, 
+click on :menuselection:`Configuration --> Delivery Methods`.
+
+First set a name and a transporter company.
+
+.. image:: media/setup03.png
+   :align: center
+
+Then you'll have to set the pricing. It can be fixed or based on rules.
+
+-  If the price is fixed, tick **Fixed price**. You'll just have to define
+   the price. If you want the delivery to be free above a certain
+   amount, tick the option **Free if Order total is more
+   than** and set a price.
+
+.. image:: media/setup06.png
+   :align: center
+
+-  If the price varies according to rules, tick **Based on Rules**. Click
+   on **add an item to a pricing rule**. Choose a condition based on
+   either the weight, the volume, the price or the quantity.
+
+.. image:: media/setup04.png
+   :align: center
+
+Finally you can limit the delivery method to a few destinations. The
+limit can be applied to some countries, states or even zip codes. This
+feature limits the list of countries on your e-commerce.
+

+    real price and packagings, and handle the printing the shipping labels.
