=head1 SYNOPSIS
-See L<Catalyst>.
+A script using the Catalyst::Engine::CGI module might look like:
+
+ #!/usr/bin/perl -w
+
+ use strict;
+ use lib '/path/to/MyApp/lib';
+ use MyApp;
+
+ MyApp->run;
+
+The application module (C<MyApp>) would use C<Catalyst>, which loads the
+appropriate engine module.
=head1 DESCRIPTION
-This is the CGI engine for Catalyst.
+This is the Catalyst engine specialized for the CGI environment (using the
+C<CGI> and C<CGI::Cookie> modules). Normally Catalyst will select the
+appropriate engine according to the environment that it detects, however you
+can force Catalyst to use the CGI engine by specifying the following in your
+application module:
+
+ use Catalyst qw(-Engine=CGI);
+
+The performance of this way of using Catalyst is not expected to be
+useful in production applications, but it may be helpful for development.
