+# Action runners deployment default example
+
+This module shows how to create GitHub action runners that run on ubuntu on EC2.
+
+## Usages
+
+Steps for the full setup, such as creating a GitHub app can be found in the root module's [README](../../README.md).
+
+This is designed to be "It just works" wrapper, if you want more configuration, the [philips module](https://raw.githubusercontent.com/philips-labs/terraform-aws-github-runner) is probably a better
+fit.
