+==================================
+How to get paid with Authorize.Net
+==================================
+
+Authorize.Net is one of the most popular eCommerce payment platforms in North America.
+Unlike most of the other payment acquirers compatible with Odoo, 
+Authorize.Net can be used as `payment gateway <https://www.authorize.net/solutions/merchantsolutions/pricing/?p=gwo>`__ only.
+That way you can use the `payment processor or merchant <https://www.authorize.net/partners/resellerprogram/processorlist/>`__ that you like.
+
+
+Create an Authorize.Net account
+===============================
+
+* Create an `Authorize.Net account <https://www.authorize.net>`__ 
+  by clicking 'Get Started'.
+* In the pricing page, press *Sign up now* if you want to use Authorize.net as
+  both payment gateway and merchant. If you want to use your own merchant, press
+  the related option.

+
+Assess Authorize.Net as payment solution
+========================================
+You can test and assess Authorize.Net for free by creating a `developer account <https://developer.authorize.net>`__.
+
+Once the account created you receive sandbox credentials.
+Enter them in Odoo as explained here above and make sure 
+you are still in *Test* mode.
+
+You can also log in to `Authorize.Net sandbox platform <https://sandbox.authorize.net/>`__
+to configure your sandbox account.
+
+To perform ficticious transactions you can use fake card numbers
+provided in the `Authorize.Net Testing Guide <https://developer.authorize.net/hello_world/testing_guide/>`__.
