+## Setup Dapr component
+To setup an Alibaba Cloud Nacos binding create a component of type `bindings.nacos`. See [this guide]({{< ref "howto-bindings.md#1-create-a-binding" >}}) on how to create and apply a secretstore configuration. See this guide on [referencing secrets]({{< ref component-secrets.md >}}) to retrieve and use the secret with Dapr components.
+
+```yaml
+apiVersion: dapr.io/v1alpha1
+kind: Component
+metadata:
+ name:
+ namespace:
+spec:
+ type: bindings.nacos
+ version: v1
+ metadata:
+ - name: endpoint
+ value: "******.mse.aliyuncs.com:8848"
+ - name: region
+ value: "cn-shanghai"
+ - name: namespace
+ value: "e525eafa-f7d7-4029-83d9-************"
+ - name: accessKey
+ value: "****************"
+ - name: secretKey
+ value: "****************"
+ - name: watches
+ value: "key1:group1,key2:group2"
+```
+{{% alert title="Warning" color="warning" %}}
+The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described [here]({{< ref component-secrets.md >}}).
+{{% /alert %}}
+## Spec metadata fields

+
+## Binding support
+
+This component supports both **input and output** binding interfaces.
+
+This component supports **output binding** with the following operations:
+- `create`
+- `get`
+
+## Create an AliCloud Nacos
+Follow [these instructions](https://www.alibabacloud.com/help/doc-detail/59963.htm) to setup AliCloud Nacos.
+ - A Chinese (simplified) version can be found [here](https://help.aliyun.com/document_detail/85466.html)
+
+## Specifying a partition key
+
+When invoking the Nacos binding, its possible to provide an optional partition key by using the `metadata` section in the request body.
+You can specifie`config-id` and `config-group` in `metadata`
+
+Example:
+
+```shell
+curl -X POST http://localhost:3500/v1.0/bindings/myNacos \
+ -H "Content-Type: application/json" \
+ -d '{
+ "data": {
+ "message": "Hi"
+ },
+ "metadata": {
+ "config-id": "key1",
+ "config-group": "group1"
+ },
+ "operation": "create"
+ }'
+```
+
+```shell
+curl -X POST http://localhost:3500/v1.0/bindings/myNacos \
+ -H "Content-Type: application/json" \
+ -d '{
+ "data": {
+ "message": "Hi"
+ },
+ "metadata": {
+ "config-id": "key1",
+ "config-group": "group1"
+ },
+ "operation": "get"
+ }'
+```
