To use this, download the binary for your specific operating system and architecture. Remove the suffix so that the file becomes just "terraform-policymaker". Then install this either in your path or in the local directory. To run, use the command:
terraform-policymaker -path=<path_to_tf_config>
You need to have permissions to run a terraform plan in your tf config path. This is because the tool requires generating an execution plan that can be used to determine which permissions are required. If any questions, please open an issue.
