+# Terraform Azure Data Factory Example
+
+This folder contains a Terraform module that deploys resources in [Azure](https://azure.microsoft.com/) to demonstrate how you can use Terratest to write automated tests for your Azure Terraform code.
+This module deploys a Data Factory.
+
+- A [Azure MySQL Database](https://azure.microsoft.com/en-us/products/data-factory).
+
+Check out [test/azure/terraform_azure_datafactory_example_test.go](./../../../test/azure/terraform_azure_datafactory_example_test.go) to see how you can write automated tests for this module and validate the configuration of the parameters and options.
+
+**WARNING**: This module and the automated tests for it deploy real resources into your Azure account which can cost you money.
+
+## Running this module manually
+1. Sign up for [Azure](https://azure.microsoft.com/).
+1. Configure your Azure credentials using one of the [supported methods for Azure CLI
+   tools](https://docs.microsoft.com/en-us/cli/azure/azure-cli-configuration?view=azure-cli-latest)
+1. Install [Terraform](https://www.terraform.io/) and make sure it's on your `PATH`.
+1. Ensure [environment variables](../README.md#review-environment-variables) are available
+1. Run `terraform init`
+1. Run `terraform apply`
+1. When you're done, run `terraform destroy`.
