+## **Remote Node Management support**
+
+Dagu supports managing multiple Dagu servers from a single UI through its remote node feature. This allows you to:
+
+-   Monitor and manage DAGs across different environments (dev, staging, prod)
+-   Access multiple Dagu instances from a centralized UI
+-   Switch between nodes easily through the UI dropdown
+
+See [Remote Node Configuration](https://dagu.readthedocs.io/en/latest/config_remote.html) for more details.
+
+### Configuration
+
+Remote nodes can be configured by creating `admin.yaml` in `$HOME/.config/dagu/`:
+
+```yaml
+# admin.yaml
+remoteNodes:
+    - name: "prod" # Name of the remote node
+      apiBaseUrl: "https://prod.example.com/api/v1" # Base URL of the remote node API
+    - name: "staging"
+      apiBaseUrl: "https://staging.example.com/api/v1"
+```

+Introduction
+-------------
+Dagu UI can be configured to connect to remote nodes, allowing management of DAGs across different environments from a single interface.
+
+How to configure
+----------------
+Create ``admin.yaml`` in ``$HOME/.config/dagu/`` to configure remote nodes. Example configuration:
+
+.. code-block:: yaml
+
+    # Remote Node Configuration
+    remoteNodes:
+    - name: "dev"                                # name of the remote node
+      apiBaseUrl: "http://localhost:8080/api/v1" # Base API URL of the remote node it must end with /api/v1
+
+      # Authentication settings for the remote node
+      # Basic authentication
+      isBasicAuth: true              # Enable basic auth (optional)
+      basicAuthUsername: "admin"     # Basic auth username (optional)
+      basicAuthPassword: "secret"    # Basic auth password (optional)
+
+      # api token authentication
+      isAuthToken: true              # Enable API token (optional)
+      authToken: "your-secret-token" # API token value (optional)
+
+Using Remote Nodes
+-----------------
+Once configured, remote nodes can be selected from the dropdown menu in the top right corner of the UI. This allows you to:
+
+- Switch between different environments
+- View and manage DAGs on remote nodes
+- Monitor execution status across nodes
+
+The UI will maintain all functionality while operating on the selected remote node.
