Auto-geometry tutorials

[madil90]

Hi,
I really like the auto geometry in the Chipmunk2D Pro. It's a really useful feature and essential for a game that I want to make. Unfortunately, I have no experience with Chipmunk2D at all and the sample code is quite complicated (Cloud Bomber and Space Patrol). I have read the ray wenderlich chipmunk tutorial and it gave me a lot of insight on simple physics in chipmunk. Are there any similar detailed tutorials on auto-geometry? If not, are there any simpler sample codes that can help me learn the auto-geometry features in steps?

Regards,
Adil
