I can't install wordpress in directory yourdomain.com?

My wordpress installation is complete, open IE enter yourdomain.com not, it is forced to enter the subdirectory path to install wordpress, ex: yourdomain.com/wp/index.php

You can help me, because I was a beginner use DreamHost first. You detailed instructions I understood. My english is not good.
