=head1 DESCRIPTION
-This documents the Maypole request object. For user documentation, see
-L<Maypole::Manual>.
+This documents the Maypole request object. See the L<Maypole::Manual>, for a
+detailed guide to using Maypole.
+
+Maypole is a Perl web application framework to Java's struts. It is
+essentially completely abstracted, and so doesn't know anything about
+how to talk to the outside world.
+
+To use it, you need to create a package which represents your entire
+application. In our example above, this is the C<BeerDB> package.
+
+This needs to first use L<Maypole::Application> which will make your package
+inherit from the appropriate platform driver such as C<Apache::MVC> or
+C<CGI::Maypole>, and then call setup. This sets up the model classes and
+configures your application. The default model class for Maypole uses
+L<Class::DBI> to map a database to classes, but this can be changed by altering
+configuration. (B<Before> calling setup.)
