Load all of the files in this bundle into a single directory on your laptop (or to a DVD or to a USB). Most any modern browser can read and display the HTML as a webpage. 
For the pages that have math operations one will note that "Javascript" is used. 
Anyone versed in basic HTML and basic Javascript can modify these web pages if desired.
Use a basic Text Editor.
Specifically on the Relay Notes page, one can open the page (with your text editor) and ADD your own relay testing notes into the appropriate "textarea". If this technique is tried then be advised to use a simple text editor and SAVE the file as simple text (with the file extension "HTML").
