Why don't I have a Documentation link in the django 1.0 admin page?

On my django 0.96 admin page, there was a "Documentation" link which led to all kinds of nice introspection features. After installing django 1.02, I no longer have this link. How can I get it back?

From stackoverflow

• You have to change a few things in your urls.py and settings.py:

  from urls.py:

  # Uncomment the admin/doc line below and add 'django.contrib.admindocs' 
  # to INSTALLED_APPS to enable admin documentation:
  # (r'^admin/doc/', include('django.contrib.admindocs.urls')),
  
  # Uncomment the next line to enable the admin:
  (r'^admin/', include(admin.site.urls)),
  

  Mitch : That gives an error when I include it. There is additional discussion about which lines should be uncommented for which django version in the comments of http://www.djangobook.com/en/2.0/chapter06/. I see the admin page fine. Just not the documentation link.

  Carl Meyer : Don't use "admin.site.urls" unless you've upgraded to a fairly recent trunk version of Django (NOT 1.0.2). You do, however, want the admin/doc/ line in your URLconf and django.contrib.admindocs in INSTALLED_APPS. Neither of those was necessary in 0.96.
