Making it my homepage

Hi everyone, my question os relatively simple. When my host allowed me to automatically install WordPress as a blog, it installs it in a /wordpress directory. Sadly, this is the whole of my side and therefore anyone who just goes to http://www.mysite.com is still getting the “Comeing soon” message.

How do I make my domain name go directly to the blog installed on my site? I feel kinda chinced, I could have just went and registered afree wordpress account and had them host it, and only registered my domain name instead of paying for hosting. Dummy me 😛

Thanks for the help!
