+
+## Component format
+
+To set up an Apache Dubbo binding, create a component of type `bindings.dubbo`.
+See [this guide]({{% ref "howto-bindings.md#1-create-a-binding" %}}) on how to create and apply a binding configuration.
+
+```yaml
+apiVersion: dapr.io/v1alpha1
+kind: Component
+metadata:
+  name: <NAME>
+spec:
+  type: bindings.dubbo
+  version: v1
+  metadata:
+    - name: interfaceName
+      value: "com.example.UserService"
+    - name: methodName
+      value: "getUser"
+    # Optional
+    - name: version
+      value: "1.0.0"
+    - name: group
+      value: "mygroup"
+    - name: providerHostname
+      value: "localhost"
+    - name: providerPort
+      value: "8080"
+````
+
+{{% alert title="Note" color="info" %}}
+The Dubbo binding does not require authentication or secret configuration by default.
+However, if your Dubbo deployment requires secure communication, you can integrate Dapr's [secret store]({{% ref component-secrets.md %}}) for sensitive values.

+
+## Binding support
+
+This component supports **output binding** with the following operation:
+
+* `create`: invokes a Dubbo service method.
+
+---
+
+## Example: Invoke a Dubbo Service
+
+To invoke a Dubbo service using the binding:
+
+```json
+{
+  "operation": "create",
+  "metadata": {
+    "interfaceName": "com.example.UserService",
+    "methodName": "getUser",
+    "version": "1.0.0",
+    "providerHostname": "localhost",
+    "providerPort": "8080"
+  },
+  "data": {
+    "userId": "12345"
+  }
+}
+```
+
+The `data` field contains the request payload sent to the Dubbo service method.
