The Ringmaster software downloaded from Juniper Networks doesn't come with the help files included. They are available as a separate download and need to be integrated after installation. Unfortunately, it's not really clear where to put them.

Downloading the help files provides you with a html.zip file, containing a html folder with a bunch of html files in it. This folder has to be placed inside the help/ subfolder of where you've installed the Ringmaster software. The default path in linux is: /opt/ringmaster/help/ . When done correctly, you will be able to access the help files via the URL http://ip-of-your-server/html/ or by pressing F1 in the Ringmaster client.
