How do you add a new app to a Django project?

You add the app's name as a string to the INSTALLED_APPS list in the settings.py file.

What happens if an app is not listed in INSTALLED_APPS?

Django will ignore the app. Its models won't be created in the database, and its features won't be available.

Why is the order of apps in INSTALLED_APPS sometimes important?

Because Django loads apps in order, and later apps can override templates or static files of earlier apps.

What file do you edit to manage installed apps in Django?

Why might the order of apps in INSTALLED_APPS matter?
