 - PennAppsChallenge - you can think of this as the entry point to our Django application. Two important files it contains is `settings.py` which contains our project settings and `urls.py` which tells our app which urls to keep an eye out for (more on this later).
 - pennapps - this is an "app" that we created beforehand which contains some starter code for you. Django projects can consist of many "apps" that are usually created with `python manage.py startapp app_name` (think an app as an isolated piece of "business logic" that work together in the overall app) but ours will only use one since our project is quite basic. You will mainly be working in this directory.

 #### URLs and Views
 Next, let's understand how the url flow works. Visit`PennAppsChallenge/urls.py`. Recall that this contains all the relevant urls to our project which is listed in `urlpatterns`. The first entry here,`path('admin/', admin.site.urls)`, tells Django to put the admin site on `/admin/` and the second entry, `path('', include('pennapps.urls'))` tells Django to include all the urls found in `pennapps.url` (`urls.py` in the pennapps subdirectory). Visiting `pennapps/urls.py` we see a similar `urlpatterns` list. Note however that these urls would not have been added to our Django application by default if we hadn't specified to include these urls in `PennAppsChallenge/urls.py`.
