want to know where can learn how to use the pyroscope UI

Hey, recently our company adopt pyroscope to help us to do continuous profiling to analysis the online issue. That's a amazing product and thanks you guys for the invaluable working. And I want to search for some materials to learn how to use the pyroscope UI, but it seems that there is no good material to study now. I would like to ask if we have relevant documents or learning materials to learn how to use UI.
