      If you think that a framework should be detected for this repository
      you could add a new rule by creating a pull request on Github
      (see https://github.com/koffeinfrei/technologist#contributing)
      or report an issue https://github.com/koffeinfrei/technologist/issues/new.
      Thanks!
