-Here's a slightly more complex example using

-    from django.core.paginator import Paginator

-        page = request.GET.get('page')
-        contacts = paginator.get_page(page)
-        return render(request, 'list.html', {'contacts': contacts})

-In the template :file:`list.html`, you'll want to include navigation between
