 # Terraform Cloud Getting Started Guide Example
 
-This is an example Terraform configuration intended for use with the Terraform Cloud Getting Started Guide hosted at https://learn.hashicorp.com/terraform/cloud/tf_cloud_overview
+This is an example Terraform configuration intended for use with the [Terraform Cloud Getting Started Guide](https://learn.hashicorp.com/terraform/cloud-gettingstarted/tfc_overview).
+
+## What will this do?
+
+This is a simple Terraform configuration that will create an empty [DynamoDB](https://aws.amazon.com/dynamodb/) table using your AWS account.
+
+When you set up a Workspace on Terraform Cloud, you can link to this repository. Terraform Cloud can then run `terraform plan` and `terraform apply` automatically when changes are pushed. For more information on how Terraform Cloud interacts with Version Control Systems, see [our VCS documentation](https://www.terraform.io/docs/cloud/run/ui.html).
+
+## What are the prerequisites?
+
+You must have an AWS account and provide your AWS Access Key ID and AWS Secret Access Key to Terraform Cloud. Terraform Cloud encrypts and stores variables using [Vault](https://www.vaultproject.io/). For more information on how to store variables in Terraform Cloud, see [our variable documentation](https://www.terraform.io/docs/cloud/workspaces/variables.html).
+
+The values for `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` should be saved as environment variables on your workspace.
