How to start using Beaker in Django

Question

Question: Could people show or point me a complete example or tutorial to start using Beaker in Django?

Information: Since I've read about problem in database connection with django orm from here. http://lethain.com/entry/2008/jul/23/replacing-django-s-orm-with-sqlalchemy/
Here is the correct link http://adam.gomaa.us/blog/2007/aug/26/the-django-orm-problem/

so I've decided to replace django orm with sqlalchemy.

And that mean I couldn't use session from django.

Beaker is look promising to me. but I don't know how to start. The Beaker document is leave me many questions

What is WSGIAPP? How to use Beaker session in my django view? and Where is the runnable example?

Could people show or point me a complete example or tutorial to start using Beaker in Django?

note: I'm using Django-1.1.1 and Beaker 1.5

Thanks
