The website app is a Django application designed to manage basic web pages within a website.

1. Add "website" to your INSTALLED_APPS in your Django project's settings:

   INSTALLED_APPS = [
       ...
       'website',
   ]

2. Include the website URLconf in your project urls.py like this:: you may want to add some url path inside the ''

   path('', include(('website.urls', 'website'), namespace="website")),

3. Run python manage.py migrate website to create the website models.

4. Start the development server and visit http://127.0.0.1:8000/admin/ to create the models (you'll need the Admin app enabled).

5. Visit http://127.0.0.1:8000 to see the website

if you want to use the article links outside the app you need to use the namespace. it is always a good idea when having many apps inside a Django project to use the namespace. for example:

> <a href="{% url 'website:URL'  %}"</a>

...

To enable user registration and authentication, follow these steps:

1. Add 'django.contrib.auth' and 'django.contrib.auth.urls' to your INSTALLED_APPS in your Django project's settings:

   INSTALLED_APPS = [
       ...
       'django.contrib.auth',
       ...
   ]

2. Include the authentication URLconf in your project's urls.py:

   path('accounts/', include('django.contrib.auth.urls')),

Now, your website should have user registration and authentication functionality. For more advanced features, refer to the Django Authentication documentation.
