@jhenderson-pro since this was a request in https://secure.helpscout.net/conversation/2021733689/29981?folderId=6841159, are you able to run with this?

[jhenderson-pro]

This will require a new docset before the release. I'll open that up tomorrow and do the two PRs. I've got most of the text completed in a local branch already.
