Django external documentation?

How do I enable external documentation for Django?  Under "Django Support", "Enable Django Support" is checked, but the documentation is not configured.  I have PyCharm 2.5.1 (evaluation mode).

On the PyCharm web site, I see:

"PyCharm knows documentation sites for the Python standard library, Django and Google App Engine."

But when I press Shift-F1 on, say, django.forms.MultipleChoiceField, I get a dialog claiming:

"Python External Documentation

No external documentation URL configured for module django.  Would you like to configure it now?"

This doesn't jibe with the claims on the web page, but I click OK.

I am zapped to the settings window, but no particular setting category is open (strange and disappointing).

I click on External Documentation.

What?  Surely I don't have to manually configure documentation for Django?
