 Django comes with a utility that can create models by introspecting an existing
 database. You can view the output by running this command::
 
-    django-admin.py inspectdb [databasename] --settings=path.to.settings
-
-...where "[databasename]" is the name of your database.
+    django-admin.py inspectdb --settings=path.to.settings
 
 Save this as a file by using standard Unix output redirection::
 
-    django-admin.py inspectdb [databasename] --settings=path.to.settings > appname.py
+    django-admin.py inspectdb --settings=path.to.settings > appname.py
 
 This feature is meant as a shortcut, not as definitive model generation. See
 the `django-admin.py documentation`_ for more information.
