+    <p>Configuration node for CLI agent integration.</p>
+    <p>This node stores connection settings for a CLI agent. Other agent nodes reference this config.</p>
+    <h3>Settings</h3>
+    <ul>
+        <li><b>CLI Command</b> - Command or full path to the agent binary. Default: <code>agent</code> (must be in PATH).</li>
+        <li><b>Workspace Directory</b> - Directory where agent will read/write files. Should be a shared volume accessible from both Node-RED and agent.</li>
+        <li><b>API Endpoint</b> - If running agent in server mode, the REST API endpoint.</li>
+        <li><b>API Key</b> - Optional authentication key for agent server mode.</li>
+        <li><b>Default Arguments</b> - Default arguments passed to the agent.</li>
+        <li><b>Max Concurrent Processes</b> - Limit concurrent agent processes.</li>
+        <li><b>Auto-start Process</b> - Start agent automatically on input.</li>
+    </ul>
+    <h3>Docker Setup</h3>
+    <p>When running in Docker, ensure the workspace directory is mounted as a volume in both Node-RED and agent containers:</p>
+    <pre><code>volumes:
+  - agent-workspace:/data/agent-workspace</code></pre>
