Deployment: run webapp without runserver?

I believe I deployed my Django webapp through digital ocean, but I have to leave terminal and run python manage.py runserver on it. I tested it and I can access the website on my phone and another computer. However, when I close terminal, runserver command stops itself and my webapp is offline. How can I keep it online?

I’m going to highlight a section of the docs for runserver

DO NOT USE THIS SERVER IN A PRODUCTION SETTING. It has not gone through security audits or performance tests.

You’re moving from a development to a production-style environment. You’re entering a topic known as “Deployment”. It is what I consider to be one of the most confusing parts of working with Django.
