[Xitami] Domain Recognition

[Dr. Gil]

Serious newbie question.  I have recently downloaded and installed Xitami's
webserver.  I have signed up for and received a personal domain.  I use
Windows ME for an OS.  I am hooked up to the internet via a DSL connection.
Now then, I have no idea in this world how to have Xitami recognize my
domain name.  Does it have to do with the network settings in my control
panel?  With my ISP?  With settings within Xitami?  What?

any and all help appreciated,
Dr. Gil
