Publishing Joomla site installed in sub folder

I have set up my domain name in DreamHost. I plan on using Joomla to create the website so I used the one-click installs to install joomla under


This is working but when I want eventually pubish the website I want to have the content under the domain name i.e.

rather than using the joomla sub-folder

What do I have to do to transfer the content from the \joomla sub folder to the \domain-name folder.
