The old manual that's still included as a file inside SAM's help folder (C:\Program Files (x86)\SpacialAudio\SAMBC\help\sam-bc.chm) might be of interest as a manual for that stuff. It has however not been updated after SAM4 and if I remember correctly, still shows the old style of menus. That said, not much has changed in the general layout of SAM since then.
For a more step-by-step guide on how to set up your first station with SAM, I can strongly recommend checking out the Spacial YouTube channel: https://www.youtube.com/user/spacial
(You'll have to search a little, their focus has shifted massively since they relabeled their cloud offering from SAM Vibe to SAM Broadcaster Cloud. Ever since, SAMBC Pro is treated like the literal step-child to the company. They keep adding minor new features and support it with maintenance updates, but there's one SAM Pro video for every 10-20 SAM Cloud videos)
If you have any specific questions, the forum is a great place to ask if you come with a little patience. (Or you can go and ask the official helpdesk for support. I can't guarantee which option is faster, but the helpdesk will at least guarantee you an initial response within one or two working days. On the forums you might have to wait two weeks to get a response if things are busy for those who frequent the forums)
