As a BA, I am trying to satisfy a requirement to provide screen level "help

All input fields have an instructions parameter which can be used to provide field level help. For screen level help you can use the instructions parameter of the formlayout.

Thanks for the answer! Any other way to do this or is that the only way?

Something we have done within our organisation is use a button on reports to access a help page for the report. So if you are using the new tempo forms you could do this on each page. So the way we did it, we first declared a local Boolean variable useHelp, then we wrote the form in a large if statement so if it was true it showed our help page, if false showed our form. We then added a non submit button to the form and to the help which set the local variable and switched the view of the form. This way the help info is only shown when it is needed

Joel, thank you very much, may be an option for us.
