# This action requires the following secrets to be set on the repository:
#   GH_USER_NAME: GitHub user whose Jenkins and GitHub token are defined below
#   GH_USER_TOKEN: GitHub user token, to be used by ncu and to push changes
#   JENKINS_TOKEN: Jenkins token, to be used to check CI status

on:
  # `schedule` event is used instead of `pull_request` because when a
  # `pull_request` event is triggered on a PR from a fork, GITHUB_TOKEN will

  # secrets, which it needs to access Jenkins API.
