+# Terraform Examples
+
+This folder contains a set of Terraform examples. These examples each
+have their own README you can read for more details on what the example
+does.
+
+To run any example, just run `terraform apply` within that directory
+if you have Terraform checked out. Or, you can run it directly from git:
+
+```
+$ terraform init github.com/hashicorp/terraform/examples/aws-two-tier
+...
+
+$ terraform apply
+...
+```
