How do I start mapping as a begginer?

[ShinyJustyZ]

I looked at other posts and videos on this topic, but I am still confused on how to do it. The main thing i'm confused about is how to open the ProMods map. Any help is appreciated! (I'm a fast learner if that is revelant)

just have all pm scs files in the mod folder and open the editor
you can open it with the startup option in steam with -edit europe
