Yeah i did try to follow that i just don't really understand what its asking at the command line part and down

When starting the server via a batchfile you can pass additional parameters like "-mod=", "-autoinit" or "-servermod="

See this vor examples:
https://community.bistudio.com/wiki/ArmA:_Server_configuration#Windows

I guess you need to search for general arma 3 dedicated server tutorials

yeh i'd say that guide is pretty sparse and incomplete >> https://vindicta-team.github.io/Vindicta-Docs/dedicated-server-setup.html

> guide is pretty sparse and incomplete
Guide assumes knowledge of how to run an arma dedicated server of course.
It's same as the fact that we assume that you know how to play arma overall, thus generic arma gameplay is not highlighted in the guide.

Also, guide is hosted at Github and you can suggest corrections by making a pull request, this is always welcome:
