GD Plugin on a specific Page on site

Hello,

I am assisting someone in creating a directory on their site. I have a decent amount of WordPress experience, but building a directory is brand new to me, so apologies in advance for any naivety!

I see how to make the GD Map as the homepage, and I see how to show GD navigation in a selected menu location.

What I am having trouble figuring out, however, is how to go about putting the directory on a specific page of the site, while keeping the existing theme (blog posts, pages, content, etc) as the “main” part of the site.

Ideally what we would like would be http://www.examplesite.com/directory where the ‘directory’ page goes to the Directory and can be accessed via the Menu/Nav Bar on http://www.examplesite.com. Does anyone know of some documentation that could help in this?

Thanks in advance!
