Terraform is a tool that allows developers to treat "infrastructure as code." Infrastructure is defined in modules, and Terraform creates/changes/destroys when changes are applied.

It's best to use this package with celotool, but if you need to run terraform commands locally:

1. Download Terraform https://www.terraform.io/downloads.html
2. Ensure you have a service account key file at the path shown in the module's provider "google" section.
3. terraform init to download anything specific to the module (i.e. GCP specific binaries)
4. terraform apply to initially deploy or upgrade
5. terraform destroy to destroy
