Hello @david_loti ...
One of the nice things about the Canvas Guides available here in the Community is that you can make suggestions to any of them if you feel there are things that are not clear, inaccurate, or need additional information. I'll use this Guide as an example:
How do I create a quiz using New Quizzes?
At the bottom of any Guide, you'll find a blue "Leave Feedback" button. This is where you can provide input for the Canvas Documentation Team, and they will review your comments to see if any modifications need to be made to the documentation. You can do this with pretty much any Guide here in the Community.
Hope this helps a bit!
