+## Enable Spring Cloud Config Server
+
+You can enable Spring Cloud Config Server when you provision an Azure Spring Apps Enterprise plan instance. If you already have an Azure Spring Apps Enterprise plan resource, see the [Manage Spring Cloud Config Server in an existing Enterprise plan instance](#manage-spring-cloud-config-in-an-existing-enterprise-plan-instance) section to enable it.
+
+You can enable Spring Cloud Config Server using the Azure portal or Azure CLI.
+

+
+1. Open the [Azure portal](https://portal.azure.com).
+
+1. On the **Basics** tab, select **Enterprise tier** in the **Pricing** section and specify the required information. Then select **Next: Managed components**.
+

+
+### [Azure CLI](#tab/Azure-CLI)
+
+Use the following steps to provision an Azure Spring Apps service instance with Spring Cloud Config Server enabled using the Azure CLI.
+
+1. Use the following command to sign in to the Azure CLI and choose your active subscription:
+
+   ```azurecli
+   az login
+   az account list --output table
+   az account set --subscription <subscription-ID>
+   ```
+
+1. Use the following command to accept the legal terms and privacy statements for the Azure Spring Apps Enterprise plan. This step is necessary only if your subscription has never been used to create an Enterprise plan instance.
+
+   ```azurecli
+   az provider register --namespace Microsoft.SaaS
+   az term accept \
+       --publisher vmware-inc \
+       --product azure-spring-cloud-vmware-tanzu-2 \
+       --plan asa-ent-hr-mtr
+   ```
+
+1. Select a location. The location must support the Azure Spring Apps Enterprise plan. For more information, see the [Azure Spring Apps FAQ](faq.md).
+
+1. Use the following command to create a resource group:
+
+   ```azurecli
+   az group create \
+       --name <resource-group-name> \
+       --location <location>
+   ```
+
+   For more information about resource groups, see [What is Azure Resource Manager?](../../azure-resource-manager/management/overview.md)
+
+1. Prepare a name for your Azure Spring Apps service instance. The name must be between 4 and 32 characters long and can contain only lowercase letters, numbers, and hyphens. The first character of the service name must be a letter and the last character must be either a letter or a number.
+
+1. Use the following command to create an Azure Spring Apps service instance with Spring Cloud Config Server enabled:
+
+   ```azurecli
+   az spring create \
+       --resource-group <resource-group-name> \
+       --name <Azure-Spring-Apps-service-instance-name> \
+       --sku enterprise \
+       --enable-config-server
+   ```

 ## Restriction
 
 There are some restrictions when you use Config Server with a Git back end. The following properties are automatically injected into your application environment to access Config Server and Service Discovery. If you also configure those properties from your Config Server files, you might experience conflicts and unexpected behavior.
