remapping a domain

I’m using dream host and was unable to install WP to my root directory of http://www.momwentcrazy.com
I created a subdirectory http://www.momwentcrazy.com/home and installed WP there.

How do I get it so if people type in http://www.momwentcrazy.com it automatically directs them to http://www.momwentcrazy.com/home
