+ansible-terraform-inventory
+===========================
+
+A dynamic inventory script for Ansible and Terraform.
+
+Quickstart
+----------
+
+To use this inventory script, you must first create Terraform resources
+using the [terraform-provider-ansible](https://github.com/nbering/terraform-provider-ansible)
+plugin:
+
+```hcl
+resource "ansible_host" "example" {
+  inventory_hostname = "example.com"
+  groups = ["web"]
+  vars {
+    ansible_user = "admin"
+  }
+}
+
+resource "ansible_group" "web" {
+  inventory_group_name = "web"
+  children = ["foo", "bar", "baz"]
+  vars {
+    foo = "bar"
+    bar = 2
+  }
+}
+```
+
+Next, use this script as your Ansible dynamic inventory script.
+
+If your Ansible playbooks are in a different directory than your Terraform
+resources, then set the `TF_STATE` environment variable to the location
+of the Terraform directory.
+
+Installation
+------------
+
+Download the latest [release](https://github.com/jtopjian/ansible-terraform-inventory/releases).
+
+Building From Source
+--------------------
+
+```shell
+$ go get https://github.com/jtopjian/ansible-terraform-inventory
+$ go build -o $GOPATH/bin/terraform-inventory
+$ ln -s $GOPATH/bin/terraform-inventory /path/to/ansible/hosts
