+## Quick install (shortest path)
+
+Run from inside this repo:
+
+```bash
+./scripts/install_watchdog_bundle.sh --install-env-example
+mkdir -p ~/.config/openclaw && cp ~/.config/openclaw/watchdog-b.env.example ~/.config/openclaw/watchdog-b.env
+sed -i 's#^WATCHDOG_B_OWNER_REPORT_TARGET=.*#WATCHDOG_B_OWNER_REPORT_TARGET=channel:YOUR_DISCORD_CHANNEL_ID#' ~/.config/openclaw/watchdog-b.env
+./scripts/bootstrap_watchdog_bundle.sh && systemctl --user daemon-reload && systemctl --user enable --now openclaw-watchdog-b.timer
+```
+
+Replace `YOUR_DISCORD_CHANNEL_ID` with the real target before enabling the timer.
