Setup Notes

• Steam credentials are never stored in the compose file — use a .env file referencing $STEAM_USERNAME / $STEAM_PASSWORD.
• The save volume (./saves) must exist before starting — run mkdir saves first.
• VNC port 5900 maps to the JunimoServer web admin. Keep it behind a firewall or reverse proxy.
• Place the generated config.json in Mods/SMAPIDedicatedServerMod/ inside your server Stardew directory.
• Profit margin affects selling prices only — it does not reduce shop purchase prices.
