 ### Terraform
 
-The Terraform module is published and maintained [here](https://github.com/kmcquade/terraform-aws-policy-sentry).
-
-* Prerequisites:
-  - Install Policy Sentry (v0.7.2 or higher)
-  - Install Terraform (v0.12.8 or higher)
-
-* Create the `main.tf` in your directory with the following contents:
-
-```hcl
-module "policy_sentry_demo" {
-  source                              = "github.com/kmcquade/terraform-aws-policy-sentry"
-  name                                = var.name
-  read_access_level                   = var.read_access_level
-  write_access_level                  = var.write_access_level
-  list_access_level                   = var.list_access_level
-  tagging_access_level                = var.tagging_access_level
-  permissions_management_access_level = var.permissions_management_access_level
-  wildcard_only_actions               = var.wildcard_only_actions
-  minimize                            = var.minimize
-}
-```
-
-* Copy and paste the contents of the `variables.tf` file [here](https://github.com/kmcquade/terraform-aws-policy-sentry/blob/master/examples/demo/variables.tf) into your directory.
-
-* Create a `terraform.tfvars` file in your directory with the following contents:
-
-terraform.tfvars:
-```hcl
-name = "PolicySentryTest"
-
-list_access_level = [
-  "arn:aws:s3:::example-org",
-]
-
-read_access_level = [
-  "arn:aws:kms:us-east-1:123456789012:key/shaq"
-]
-
-write_access_level = [
-  "arn:aws:kms:us-east-1:123456789012:key/shaq"
-]
-```
-
-* Run `terraform apply` once to create the JSON policy file.
-
-* Run `terraform apply` **again** (from the same directory) to create the IAM policy.
-
-For the full example, including GIFs depicting real output, see the README for the Terraform module [here](https://github.com/kmcquade/terraform-aws-policy-sentry).

 Builds secure IAM Policies with resource constraints. For more information on Policy Sentry, see [the documentation](https://policy-sentry.readthedocs.io/en/latest/).
 
 ## Prerequisites
 
 * You must have Policy Sentry 0.10.0 installed beforehand and it must be executable from your `$PATH`. Follow the installation instructions [here](https://policy-sentry.readthedocs.io/en/latest/user-guide/installation.html)
-  * This module currently requires Terraform 0.12.8
+  * This module requires Terraform 0.12.8 or higher. It has been tested through 0.13.5.
