Description
Project: 
Ubercart

I don't see any readme in the v3 version. I've installed:
1. module

2. the dependent jquery plugin- Jquery Colorpicker

3. colorpicker.zip file to put in my sites/all/libraries.

But there are no instructions anywhere and I'm not finding anything on my product node pages.

Help?
Thanks.

apologies in advance for the cross-posting
