Documentation

All modules or deployments of Terraform should contain documentation that explains the purpose or describes usage of resources. This is usually in the form of a README within each directory/repository.

Terraform-docs

Terraform-docs is a utility which can be used to automate the generation of documentation files for each terraform deployment.
The website contains a guide on how to install, as well as how to use the utility via CLI, GitHub actions or via pre-commit hook.
