Need specific help with domain-mapping plugin

I am having trouble understanding how to set-up CNAME and ANAME for leadthepack.reallyresonablewebsites.com the actual domain I want to map is leadthepackongoogle.com

I am a newbie and using this plugin for the first time.

Just need to know: The NAME and the CNAME I should put in the form in the Cpanel advanced DNS records.

Once you provide, I’ll be able to do this from now on for any other subdomain.
