AsCode Github Action allows to execute AsCode `run` command in response to a GitHub event such as updating a pull request or pushing a new commit to a specific branch.
This used in combination with the [Terraform GitHub Actions](https://www.terraform.io/docs/github-actions/getting-started.html) allows to execute the different terraform commands `init`, `plan` and `apply` inside of a [GitHub Workflow](https://help.github.com/en/actions/configuring-and-managing-workflows).
