+
+## Secrets (1Password)
+
+Item `project-zomboid` in `homelab-prod` vault:
+
+| Field | Purpose |
+|-------|---------|
+| `admin-username` | In-game admin login |
+| `admin-password` | In-game admin password |
+| `server-password` | Password players need to join |
+| `rcon-password` | RCON remote admin password |
+
+## First Boot
+
+First boot takes 5-10 minutes as the server loads all B42 assets and generates the world. The `sed` warnings about missing `.ini` are normal on first boot — the file is created after the JVM starts.
+
+## Server Config
+
+Server config is stored on the PVC at `/home/steam/Zomboid/Server/VanillaX.ini`. Changes to this file persist across restarts.
