How to add second domain from GoDaddy to FatCow 2014

I have been using FatCow to host my websites for more than 5 years. My experience with this hosting company is good. FatCow offered unlimited hosting but the primary reason for me is the adequately and professionally supports of this company.

I have bought another domain from GoDaddy and added this new domain to the primary domain on Fatcow by domain pointing.
