Have you ever heard of "reverse engineered clean room" design?
The idea is that the basic idea is the same as something you don't have, like a page they have written in your own words, at least the intro description if nothing else.
Past that, pretend the original page does not exist and hunt down examples YOU are personally able to write entirely on your own without even looking twice at TV Tropes.
The end result is a page the covers the same basic idea as theirs, but is so overly written in your own words without writing a ripoff of their content based on what you can discover without their page as a guide you will easily be able to claim your work is not in violation of copyright.
Copyright law works on the principle that a comparison of your work is just original enough they can't claim you ripped off anything more than, at most, the basic idea, like they designed a wall phone and yours is placed on a table, but they both serve as phones.
However, if the documentation you write for your phone is done without basically rewording their documentation, they can't claim you did anything more than come up with another form of phone, which, basic concept aside, shares so little with their work they can't call you a thief because you come up with it without using their phone as a guide.
