+# NexusOps — Central Agent Control Dashboard
+
+> Central control and monitoring dashboard for a fleet of autonomous AI agents: live node status, agent registration and heartbeats, remote commands, log capture, and CSV export via a JSON REST API.
+
+## What It Is
+NexusOps (network-node-dashboard) is the operator console for a distributed network of AI agent nodes. Agents register, heartbeat, post logs and results; operators watch status, pull logs, and export data as CSV. JSON REST API; the dashboard UI itself requires an auth token when enabled.
