+# Proxmox LXC Game Server Pattern
+
+## Container Setup
+- Unprivileged container with `nesting=1`
+- No Docker needed, so no keyctl/apparmor hacks required
+- Template: Debian 12
+
+## SteamCMD Setup
+```bash
+dpkg --add-architecture i386
+apt install lib32gcc-s1 steamcmd
+```
+
+## User
+- Create dedicated `steam` user for server process
+- Run SteamCMD and server as `steam`, not root
+
+## SteamCMD Invocation Pattern
+```bash
+steamcmd +@sSteamCmdForcePlatformType linux +login anonymous \
+  +force_install_dir /home/steam/server \
+  +app_update <APP_ID> validate +quit
+```
+
+## Systemd Service Pattern
+```ini
+[Service]
+Type=simple
+User=steam
+Restart=on-failure
+ExecStart=/home/steam/server/start.sh
+```
+
+## DNS
+- Use local gateway/Pi-hole (e.g. 10.10.0.1) not 8.8.8.8
+- Set via: `pct set <CTID> --nameserver 10.10.0.1`
+
+## GPU
+- No GPU passthrough needed for headless game servers
+
+## Reference
+- Existing LXC creation script: `gaming/scripts/lxc-docker-create.sh` (adapt, minus Docker parts)
