+# Notes
+
+Beszel is a lightweight server monitoring platform that includes Docker statistics, historical data, and alert functions.
+
+The hub (this compose file) provides the web UI and communicates with agents installed on each monitored system. The agent can either be installed as a standalone binary or as a separate Docker container (see the Beszel docs for agent setup options).
+
+After starting the hub, create your admin account by visiting `http://localhost:8090` and navigating through the initial setup. Then add your systems via the dashboard and deploy the agent on each host you want to monitor.
+
+> [!NOTE]
+> Make sure the agent port (default `45876`) is reachable from the Beszel hub. For agent-only deployments on the same host, see the `extra_hosts` approach documented upstream.
