Making A Keyboard Replacement Guide...

I am going to replace 4 keyboard on 4 MB Air Models I have noticed there is actually no guide on how to do this. There are many steps involved so:

Question 1: Can I simply copy everything from an existing guide to use as a kind of template, and just add the missing steps creating a new guide?

Question 2: As this will cover all A1369 A1370 A1465 & A1466 models how or where to add the guide? As many other models where the process will be somewhat different or even not possible at all. Do I copy the guide to every model that it is applicable to (6x MacBook Air 11" models 2010-15 & 7x MacBook Air 13" models 2010-2017)?.

Question 3: 2013/14/15 13" models use the same guide for MacBook Air 13" Mid 2013 Logic Board Replacement / MacBook Air 13" Early 2014 Logic Board Replacement / MacBook Air 13" Early 2015 Logic Board Replacement, but 2017 does not have one added even though it is the exact same layouts. So, Q3 is how to copy a complete guide to add it there, thus completing the guides for that particular years model as imo it makes perfect sense to add it.

I am hoping @krisrodriguez can provide.an answer to all 3 questions, thanks in advance.
