It seems that the build step is not documented in the GitHub repository.
      The introduction text just mentions

      build other projects (workflow or freestyle)

      but the build step is neither used nor explained anywhere (tutorial etc.).

      Coming from the Build Flow plugin, I'd say it's an important step and should be documented.
