How to get the startup tutorial of B78X

I want to learn the aircraft start-up and CDU settings of B78X. Where can I find the official tutorial document?

Hi occto77,

This forum is for developers working with the sim SDK. Users of the sim are better served by the regular MSFS forums: https://forums.flightsimulator.com/

You can find all the aircraft manuals at Aircraft Manuals - Microsoft Flight Simulator.
