+# Using Terraform with AWS
+
+This directory contains a number of subdirectories with example configurations intended to help users understand how to use Terraform ([http://terraform.io](http://terraform.io)) with AWS. All of these example configurations require a working Terraform installation and access to a valid AWS account.
+
+## Contents
+
+* **README.md**: This file you're currently reading.
+
+* **simple-ec2**: This directory contains a simple Terraform configuration for spinning up an Ubuntu 14.04 EC2 instance in an account's default VPC.
+
+## Prerequisites
+
+These instructions assume you've already installed Terraform and that you have access to a valid AWS account. Installing Terraform and/or working with AWS accounts are not covered in any of these materials.
+
+These environments were tested with Terraform 0.7.7. Earlier versions may or may not work; I recommend upgrading your version of Terraform to 0.7.7.
