How to make Django serve static files with Gunicorn?

I want to run my django project under gunicorn on localhost. I installed and integrated gunicorn. When I run:

python manage.py run_gunicorn

It works but there are no any static files (css and js)

I disabled debug and template_debug in settings.py (made them false), but it is still same. Am I missing something?

I call statics like:

{{ STATIC_URL }}css/etc....
