   In the Cloud Shell

   1. In the Cloud Shell, review the cosmosDB.tf.
   2. Make note of the resource group name and label at the top and then close the file.
   3. Run the az group list command to get the subscription id.
   4. Import your resource group into Terraform using the resource group name, label, and subscription id.
   5. After the import, add the name and location of your resource group to the cosmosDB.tf file so it looks like the code below (fill in with your resource group and location):

      resource "azurerm_resource_group" "super-vote" {
          name     = "<RESOURCE_GROUP>"
          location = "<LOCATION>"
      }
