+# Terraform Docker Image
+
+This repository is for building a container image that uses a simple terraform
+wrapper to work on terraform files mounted in the `/home/terraform/source`
+directory. It is also the image base for creating custom terraform images
+with special plugins preloaded onto the image.
+
+## Building
+
+Create a container with a specific version of terraform
+
+```bash
+docker build -t terraform:0.13.0 --build-arg TERRAFORM_VERSION=0.13.0 .
+```
+
+## Usage
+
+Mount the current directory as the terraform source and run the show command
+
+```bash
+docker run -v $(pwd):/home/terrform/source terraform:0.13.0 show
+```
