-When `github-report` is enabled, the action asks Checkly whether the Checkly
-GitHub App is connected to the repository and can report GitHub Checks. If it is,
-the action runs the CLI with `--detach`, passes GitHub Actions metadata to the
-CLI, and Checkly posts a GitHub Check that updates when the session finishes.
-
-If GitHub Check reporting is unavailable, the action runs without `--detach` and
-waits for the test session to finish so the GitHub Actions job reports the
-result. It also uses the CLI GitHub reporter and writes the Checkly summary to
-the GitHub Actions step summary. Install the
-[Checkly GitHub App](https://github.com/apps/checkly) on the repository to run
-detached and receive a Checkly GitHub Check instead.
+The `reporting` input controls where the Checkly result is reported:
+
+- `auto` (default): use a detached run with GitHub Check reporting when the
+  Checkly GitHub App can report on the repository. Otherwise, wait in the
+  GitHub Actions job and report there.
+- `github-check`: require detached GitHub Check reporting. The action fails
+  before running checks if the Checkly GitHub App cannot report on the
+  repository.
+- `github-actions`: always wait in the GitHub Actions job and report through the
+  CLI GitHub reporter and step summary.
