  # This is a sample workflow that you can replace with your source code

  # The workflow does the following:
  # - Retrieves the current date from a public API and stores the
  #   response in `currentDate`
  # - Retrieves a list of Wikipedia articles from a public API related
  #   to the day of the week stored in `currentDate`
  # - Returns the list of articles in the workflow output
  #
  # Note that when you define workflows in Terraform, variables must be
  # escaped with two dollar signs ($$) and not a single sign ($)
