While I'm not new to the world of design I am a complete newb when it comes to servers. I've been looking for in depth tutorials for setting up my own webserver but have managed to find anything that is concise with step by step details. 

Everything is setup. I have a computer with turnkey lamp stack installed, i've entered webmin using my root passwd. Localhost works fine. Mainly what I want to know is what I need to do to attribute the domain name I've secured through the webserver I've set up. Probably something extremely simple I'm overlooking. Any help or at the least pointing me in the right direction would be greatly appreicated.
