WooCommerce Compatibility?

I have WordPress 3.7.1 and Attitude 1.2.4 installed.

I then installed WooCommerce but got the following message:

Your theme does not declare WooCommerce support – if you encounter layout issues please read our integration guide or choose a WooCommerce theme

I was wondering if anyone has successfully integrated Attitude with WooCommerce?

What changes (if any) do I need to make to WooCommerce to make it work with Attitude?

Cheers
