Help page menu

We use the Apple TV plus ext HDD with iTunes for our educational meditation audios and videos in our meditation centres around Australia.
To help our trainers locate the appropriate content we use the iTunes playlist feature.
We’d like to have a Help menu included on the ATV’s main menu which could be used as  a User Guide to assist our trainers.
The Help menu would list .txt files uploaded to a “Help” folder on the ATV. Selecting a Help file would display the contents of appropriate .txt file.
