How to add a new domain

[koko92_national]

Hello i'm not sure if this is the right category to post this thread but i have a question. I've succesfully installed ISP OMEGA and its great, but when i enter my domain name the host panel says that the website is under reconstruction or something like that. And i was asking where to put my site (because i dont see any folder like htdocs) and how to add new domain names to my server and last how to configure bind for the new domains? Thaks
