Using discourse purely for Q&A functionality without UI or Authentication

Awesome! Thanks so much for answering my questions so far! I was looking at the cloud installation instructions here: discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub. I attempted to follow these instructions to setup the production build locally to test out simple interactions. However, the instructions mention that I can’t use IP address to access the app. What should I use instead if i intend to run the app locally?
