I am not finding any documentation on how to best use / apply this plugin and would like to check compatibility with current software versions is OK, and where any guides may be as to how to best utilise this very useful sounding plugin? Thank you.

It is a pretty simple plugin. You only need to incorporate the details of your site in the plugin settings. It does not need any special settings. Please see the below screenshot to learn more.





You only need incorporate your information in the plugin settings and you are ready to go. "Exclude Views" option can be used if you need to exclude any component views from the scope of the plugin and you can keep it blank.
