Install Factorio mods

Every player needs the same mods at the same versions. Factorio checks this when someone connects and refuses a mismatch, so set up the server first and have everyone match it.

1. Stop the server.
2. Download the mod zips from the in-game mod portal or from mods.factorio.com.
3. In Files, open the mods folder (create it if it isn't there) and upload the zips. Keep the original filenames: Factorio uses the version number in the name to sort out dependencies.
4. Upload the dependencies too. Big overhauls like Krastorio or Space Exploration pull in several libraries and won't load without them.
5. Start the server. The console lists every mod it loaded.
