Fixed #8150 -- Updated a reference to creating an admin class in the overview

Once your models are defined, Django can automatically create a professional,

production ready :ref:`administrative interface <ref-contrib-admin>` -- a Web

site that lets authenticated users add, change and delete objects. It's as easy

as adding a line of code to your model classes::

as registering your model in the admin site::

    # In models.py...

    from django.db import models

    class Article(models.Model):

        pub_date = models.DateTimeField()

        content = models.TextField()

        reporter = models.ForeignKey(Reporter)

        class Admin: pass

    # In admin.py in the same directory...

    import models

    from django.contrib import admin

    admin.site.register(models.Article)

The philosophy here is that your site is edited by a staff, or a client, or

maybe just you -- and you don't want to have to deal with creating backend
