1. Go to manage domains under your account at godaddy
2. There click on your domain, or check the box next to the domain name you want to configure
3. That will highlight and enable a few options at the top.
4. Click the nameserver option.
5. Check the custom namesever option from the available ones.
6. You will see some nameserver settings by default. Change that to
NS1.X10HOSTING.COM
NS2.X10HOSTING.COM
7. Come back to your Cpanel at x10.
8. Add it as a sub domain (not parked)
9. That it, done.
Give some time for everything to setup. Or if you are in a hurry, flush your dns and open your website.
If you are lucky enough, you should see your website showing the cgi-bin folder.
Hope this helps
