Errbot: Как правильно настроить новые плагины?

Я пытаюсь следовать руководству Errbot, чтобы создать новый плагин HelloWorld. Однако после того, как мой errbot успешно подключился к HipChat, я не могу увидеть новый плагин, который я создал. Это вывод DEBUG из консоли.

Я просмотрел этот вопрос но это не очень помогло.

Вот код для helloworld.py

from errbot import BotPlugin, botcmd, arg_botcmd, webhook

def activate(self):
    """
    Triggers on plugin activation

    You should delete it if you're not using it to override any default behaviour

    super(Helloworld, self).activate()

    """
    Triggers on plugin deactivation

    You should delete it if you're not using it to override any default behaviour
    """
    super(Helloworld, self).deactivate()

def get_configuration_template(self):
    """

    You should delete it if your plugin doesn't use any configuration like this

           }

def check_configuration(self, configuration):
    """

    pass

@webhook
def example_webhook(self, incoming_request):
    """A webhook which simply returns 'Example'"""
    return "Example"

# Passing split_args_with=None will cause arguments to be split on any kind
# of whitespace, just like Python's split() does
