 ## How does this CI/CD work?
 There is a custom GitHub Actions (`./github/actions/terraform/action.yaml` file) action that is used to run terraform plan and apply commands in a given environment, please check the `./github/workflows/main.yaml` file to understand how this is being used. A `ci` Job was also created to validate formating, linting and security issues.
