Where can I download a PDF a Monterey User Guide

Monterey has not been released yet, so no official documents about it for the public.

Once it's on, you'll be able to find the user guide here macOS User Guide - Apple Support

I just purchased my 1st MacBook Pro 16" (New Release) and am looking for a PDF Users Guide since my experience is with Windows PCs.

I suspect you will see no documentation until macOS Monterey is released on the general public 10/25
