+to [60 requests per hour per IP](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting). If

-## Recommended permissions
-
-When using the `setup-go` action in your GitHub Actions workflow, it is recommended to set the following permissions to ensure proper functionality:
