  # ### CI Setup
  #
  # Add a script step to your workflow:
  # ``` yml
  # - script@1.1.2:
  #     inputs:
  #    - content: |-
  #        bundle install
  #        bundle exec danger
  # ```
  # ### Token Setup
  #
  # Add the `DANGER_GITHUB_API_TOKEN` to your workflow's App Env Vars.
  # Warning: adding the token as a Secret Env Var will not work for PR builds, as [Bitrise does not expose secret vars to PRs](https://bitrise.uservoice.com/forums/235233-general/suggestions/11701587-make-secret-env-variables-available-for-prs-from-t).
