Matching just /docs created a very small namespace, since any other path parts would match the Document path. So, append /show after /docs for the display view. This makes other views like /docs/edit possible later.

from django.conf.urls.defaults import *

urlpatterns = patterns('',
    (r'^$', 'examples.views.index'),
    (r'^hello/', include('examples.hello.urls')),
)
