Go into the control panel for your domain (at your domain host). Set the nameservers to ns1.x10hosting.com and ns2.x10hosting.com. Once that's done, log in to your x10hosting.com account cPanel. Go to the Parked Domains option, it's relatively near the top (if not in the first row). You will see a text box with a button next to it saying Park Domain. Enter your domain into that text box (without www. so it would be just name.com or .net or whatever you have). And click Park Domain. Wait for it to load, once it's done... navigate to your domain in around 5 minutes and it should take you to your site.
