Detailed Installation Guide for Directory – not working

I want to keep my site as it is, but add the Directory to a specific page. I don’t know how to do this and when I click on the Detailed Installation Guide nothing happens.

This is the first time I’ve had to load anything via a FTP application and am so pleased with how smoothly it went!

Can’t wait to get Directory up and running. Your help for a self-taught newbie would be appreciated. Thank you.
