Accessibility Help Website

Create a public access website that lists all of the accessibility features available in a Geocortex Essentials map (e.g. screen reader, keyboard shortcuts).  I've only been able to find this information in the Viewer Administrator Guide.  I'd like to be able to add a web link to my map that will direct people to a website that describes how to use the accessibility features.  Right now, I had to create my own document.
