What is the difference between -mod and -serverMod?

-mod loads mods players must also have; -serverMod loads server-side-only mods that clients don't need.

Why quote the mod lists?

The semicolon is a separator in the shell: without quotes the line would be cut. The tool adds them automatically.

How to use Arma 3 launch parameters generator?

The Arma 3 server is driven by command-line parameters. This tool writes a readable script, one parameter per line, with mod lists separated by semicolons and properly quoted.

Choose Linux (start.sh) or Windows (start.bat), then the name, port (2302 by default) and the server.cfg / basic.cfg files.
List your mods (one @mod folder per line) in -mod, and server-only mods in -serverMod.
Enable -autoInit and -world=empty to automatically load the first mission from server.cfg.
Download the script, put it in the server folder and run it (chmod +x start.sh on Linux).
