Could somebody help me execute the scheduling spiders using djcelery?

Every time i run the command mentioned in the django dynamic scraper's documentation after creating periodic tasks, i'm getting this error.

(venv) H:\example_project>python manage.py celeryd -l info -B --settings=example_project.settings
H:\example_project\venv\lib\site-packages\celery\app\defaults.py:251: CPendingDeprecationWarning:

-B option does not work on Windows. Please run celery beat as a separate service.

Could somebody help me fix this? I'm a newbie and this is a part of my final year project.
