dddddecorating

Hiya, Hosting noob here — I believe I'm supposed to request the addition of a domain I've registered, in order to have it correctly resolve at HelioHost? My username is Dddddecorating, and the domain to add is: dddddecorating.com The nameservers have been updated at my registrar's admin—is there anything else I need to do here on the HelioHost end (besides upload files) to properly point traffic to the domain? Thanks!
