    ======================================================================

    #{logo}

      Congrats on your fine choice of authentication library, friend.


      Instructions:
        1. add the following line to the end of your config/config.exs:

                      --> #{file} <--

        2. run `mix hr.gen.model [Singluar] [plural]` if you haven't
           already (or follow the instructions to add HR to an existing
           Model)
        3. Enjoy your easy life of not writing dumb authentication code #{heart}
