It's a start.
We need to have a Wiki set up with tutorials like mine put on it. Then other people can contribute to it.
Of course, the Wiki needs to use the CR, so we can backtrack if someone screws things up 😊
I believe the revisions are not currently exposed to the UI of the Wiki.
In any case, I would start with my CR docs, and email me if you have any text you'd like to add or change on them:
