  # ### CI Setup
  # You need to edit your `.cirrus.yml` to include `bundler exec danger`.
  #
  # Adding this to your `.cirrus.yml` allows Danger to fail your build, both on the Cirrus CI website and within your Pull Request.
  # With that set up, you can edit your task to add `bundler exec danger` in any script instruction.
