+# Provision a SQL Database
+
+This sample creates a SQL Database at the "Basic" service level.  The template can support other tiers of service, details for each service can be found here:
+
+[SQL Database Pricing](https://azure.microsoft.com/en-us/pricing/details/sql-database/)
+
+## main.tf
+The `main.tf` file contains the actual resources that will be deployed. It also contains the Azure Resource Group definition and any defined variables. 
+
+## outputs.tf
+This data is outputted when `terraform apply` is called, and can be queried using the `terraform output` command.
+
+## provider.tf
+Azure requires that an application is added to Azure Active Directory to generate the `client_id`, `client_secret`, and `tenant_id` needed by Terraform (`subscription_id` can be recovered from your Azure account details). Please go [here](https://www.terraform.io/docs/providers/azurerm/) for full instructions on how to create this to populate your `provider.tf` file.
+
+## terraform.tfvars
+If a `terraform.tfvars` file is present in the current directory, Terraform automatically loads it to populate variables. We don't recommend saving usernames and password to version control, but you can create a local secret variables file and use `-var-file` to load it.
+
+## variables.tf
+The `variables.tf` file contains all of the input parameters that the user can specify when deploying this Terraform template.
