Getting WordPress to use the root domain

I currently run my site at the URL http://smoothproductionz.com

but I have built the updated site at http://smoothproductionz.com/2013.

How do I get the content for the /2013 site to show up when you enter http://smoothproductionz.com.

Note: I am very new at coding and WP and I understand this is probably a very simple answer, but I NEED some Help
