How to Configure Domain Mapping Plugin with Godaddy

Hello,

I have this working with my namecheap.com registrar however one of my clients is using Godaddy.

The website on the network is http://www.edmontonlawpro.simplpress.com

His domain is http://www.edmontonlawpro.ca

Do I need to only create A records or do I need to create a cname record as well?

Thanks,

Matt
