how I use the domain I bought the altervista

I bought a domain and want to use it ... how do I do this

You have registered a domain, but only in Domain Parking mode, so you can't do anything useful with your domain. You have to add the DNS Management.

what i do this?

You can do this in AlterVista Control Panel -> AlterSite -> Manage Your Domains -> Add new services
