      # You might pass Router/History options as the second parameter.
      # Chaplin enables pushState per default and Backbone uses / as
      # the root per default. You might change that in the options

    # Override standard layout initializer
    # ------------------------------------
    initLayout: ->
      # Use an application-specific Layout class. Currently this adds
      # no features to the standard Chaplin Layout, it’s an empty placeholder.
      @layout = new Layout {@title}

    # Instantiate common controllers
    # ------------------------------
    initControllers: ->
      # These controllers are active during the whole application runtime.
      # You don’t need to instantiate all controllers here, only special
      # controllers which do not to respond to routes. They may govern models
      # and views which are needed the whole time, for example header, footer
      # or navigation views.
      # e.g. new NavigationController()

    # Create additional mediator properties
    # -------------------------------------
    initMediator: ->
      # Create a user property
      Chaplin.mediator.user = null
      # Add additional application-specific properties and methods
      # Seal the mediator
      Chaplin.mediator.seal()
