I agree, a beginner's guide would be very useful. A step-by-step guide starting from opening it for the very first time and an overview of the things you can do with it and how to do them. I've watched videos on WT+, but when I watch a video they will start talking about things that are too far ahead or assume you know something, and therefore it's frustrating.
A 101-level getting started guide. No jargon, no coder talk, just explain how to use it and some of the things one can use it for. Some simple examples, such as finding unsourced profiles in my location.
