Move Blog Home Page to Root after installed in a folder

I installed wordpress in a folder inside my root folder. My blog is up and running but I had to add a redirect page at my web address to get my users to my main page of my blog.

When users type http://www.mysiteaddress.com, they currently see a temporary page and get forwarded to http://www.mysiteaddress.com/myblog what is the least complicated/best way to fix this problem so that when they type http://www.mysiteaddress.com they automatically see my blog without being forwarded to it.

Thanks!
