      # simple_form.{namespace}.{model}.{attribute}

      # Namespace is used for :labels and :hints.
      #
      # Model is the actual object name, for a @user object you'll have :user.
      # Action is the action being rendered, usually :new or :edit.
      # And attribute is the attribute itself, :name for example.
      #
      # The lookup for nested attributes is also done in a nested format using
      # both model and nested object names, such as follow:

      # simple_form.{namespace}.{model}.{nested}.{action}.{attribute}
      # simple_form.{namespace}.{model}.{nested}.{attribute}

      #
      # simple_form:
      # labels:
      # user:
      # new:
      # email: 'E-mail para efetuar o sign in.'
      # edit:
