Tutorial for Wolves of Steel

[jaxa]

As a long time SH3/GWX player I still think it's the best subsim ever made, but wanna give a next try for SH5, especially when I saw mega mods for it. I've installed stock SH5 and mega mod Wolves of Steel. And here is the problem - there is no tutorial for it, similar to GWX tutorial (IMHO one of the best tutorials for any sim).
Is there any info, readme or manual how to play it, engage targets or enable and use mods included in it (for instance Church's Compass Dials Mod - I don't see it in the game) in WoS?

Last but not least - how to force crew to going down when I wanna dive the boat? Clicking buttons on the left shows info that there are people on the bridge.
