title: Integrating a payment gateway with Django-Oscar?
body: <p>I want to integrate a payment gateway with oscar. I have integrated <a href="https://github.com/django-oscar/django-oscar-paypal">oscar-paypal</a> it works fine. Should I follow oscar-paypal and try to emulate it ? 
  <a href="http://django-oscar.readthedocs.org/en/latest/howto/how_to_integrate_payment.html">This document</a>  doesn't gives the starting information but not exactly ? </p>
  
  <p>I need this. To create order, change basket status, make payments, send email, and many other steps that oscar-paypal is doing.</p>
