 Run `terraform init` (if this is a new working directory) followed by `terraform apply` to install Azure Container Storage on the targeted cluster.

 The default Elastic SAN capacity provisioned with this storage class is 1 TiB.
 
+Alternatively, you can create the storage class using Terraform.
+
+1. Use Terraform to manage the storage class by creating a configuration like the following `main.tf`. Update the provider version or kubeconfig path as needed for your environment.
+
+    ```tf
+    terraform {
+      required_version = ">= 1.5.0"

 ### Create a storage class with custom Elastic SAN capacity
 
 If you need a different initial capacity than the default 1 TiB, set the `initialStorageTiB` parameter in the storage class.
