Name servers&cPanel question

[Tro0y]

hello Firstly i’m absolutely new to this web hosting and domain thing, I was blogging on platforms like Blogger before so I need a bit of advice now
I registered some domains without webhosting on godaddy some weeks ago and today I started with the Baby plan here at hostgator.When I was asked whether I had an existing domain already I put one of my existing domains there and as been told in the welcoming e-mail I changed the name servers address from xs12/3.yyyyy.com to xy98/9.hostgator.com. Do I have to do anything else, like changing any other detail at my domain hosting? And how can I access those additional domains from my control panel? Because my initial domain is now up and running from the Cpanel but I can’t see the rest.
I changed the other domains name servers address to xy98/9.hostgator.com as well. Is it right that way? I mean from now on I have to use only these 2 adresses to every domain I register?
thx in advance

If you login to your cPanel and click "Addon Domains" you can add your other domains there

For the other domains you registered on Godaddy, you will use the same nameservers as your primary domain. But you now need to make those other domains "addon" domains on your HG account. Go to the cPanel, and click on "Addon Domains."
