Exporting Server Packages
Install all the mods you wish to run on your own game
Start up your game and go to the Mod Manage option
Active all the mods you wish to run on the server. Please note everyone joining will need to have these same mods installed on their own clients to be able to join the server
Once you have enabled the mods, open up the console (~) and run the command export_server_packages
This will export the server_packages.sii and server_packages.dat to your game's Documents folder

Stop your server using the Stop button
Click the File Manager button and navigate to ./userfiles/American Truck Simulator/ or ./userfiles/Euro Truck Simulator 2/ depending on which game you are running.
Delete or rename the current server_packages.sii and server_packages.dat files
Upload your exported server_packages.sii and server_packages.dat from your game's Documents folder to the server
Start the server back up
