-Digger is Github Action that runs Terraform `plan` and `apply` with PR-level locks
+Digger runs Terraform jobs in the CI/CD system you already have, such as Github Actions.
 
-Unlike Terraform Cloud or Spacelift, terraform jobs run natively in your Github Actions - no need to share sensitive data with another CI system
+CI/CD for Terraform is [not easy](https://itnext.io/pains-in-terraform-collaboration-249a56b4534e). This is why Terraform Cloud, Spacelift and Atlantis are essentially standalone full-stack CI/CD systems.
 
-Unlike Atlantis, there's no need to deploy and maintain a backend service.
+But why have 2 CI systems? Why not reuse the existing CI infrastructure? Digger does just that.
