Box2D

Hi Guys
Is there a good example of how to use Box2D instead of Chipmunk with cocos2D in a
Windows 8 App.

Please Help Guys
Thanks
Ronak

Have you looked at the samples?

I downloaded the win8 project which had the template and everything compiled it looked fine and good,
but I am still very lost on how to start the project,
I created a sprite with an image but that sprite is rectangle even though my image is a triangular shape png?
how can I link it to or make it have a physics body with box2D.
my knowledge of game building in very very limited.

I know this may seem noobish, but I guess I am.
