Pointing my domain at the subfolder

During my one-click install, I created a subfolder for the joomla! install.

in order to get to website, I have to add “/joomla” to the end of my domain.

How do I make the actual domain (www.deltarealinvestments.com) point to the subfolder where all the work is being done (www.deltarealinvestments.com/joomla)?

Thank you for any help you can provide.

Okay…I think I asked the question wrong.

After we finish with the design of the site, how do we launch it using Joomla?
