@Court72 ... Adding @JimacoMS4 who has been working on these docs recently. Hold off for now. Let's figure out the best place to put this kind of information (assuming we don't already have it somewhere).

@elainajones Thank you for your submission. There are some good ideas in this PR that we will want to apply more broadly, and some that we do not want to include. So, thank you again, great ideas and it brought to light the need to add a few things to certain docs ... so I'm going to close this PR, but this helped highlight some areas in our docs that can be improved. Thank you!
