Well I buyed a doain to horatio and neither him neither me understand how to install the damn domain ^^ so maybe some1 can b enought nice with yr frnd sam and tell me xD He saids something of domain name servers and 2 url servers, and dns lol
well if u mean a domain like .com or any . , u dont really install it but assign it to ur server. It kinda hard to explain without more info from u so it u will be kind enough to tell us more info like where u bought the domain from and what site/server u want to put on but i wil give it my best try the person/site should of gave u an account which u use to log in into thier site were their should be a control panel or my service thing(depend on the site selling the domain) and u put the ip adddress of the server/site u want to domain to be on. and if u bought the domian forom a site u can contact them and they will tell u how or it might be in there help or support section of their site
