+
+If you are going to use Terraform to set up the infrastructure on AWS, you first need to install the "Terraform CLI":https://developer.hashicorp.com/terraform/tutorials/aws-get-started/install-cli and the "AWS CLI":https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html tool. Then you can initialize the installer.
