 =head1 NAME
 
-Catalyst::Manual::Tutorial - Getting started with Catalyst
+Catalyst::Manual::Tutorial - Catalyst Tutorial: Overview
 
 =head1 DESCRIPTION
 
-This document aims to get you up and running with Catalyst.
-
-NOTE: THIS DOCUMENT IS STILL VERY MUCH IN AN EARLY DRAFT STATE.  SEE 
-THE NOTES AT THE BOTTOM OF THE DOCUMENT.
-
-=head2 Installation
-
-The first step is to install Catalyst, and the simplest way to do this 
-is to install the Catalyst bundle from CPAN:
-
-    $ perl -MCPAN -e 'install Bundle::Catalyst'
-
-This will retrieve Catalyst and a number of useful extensions and 
-install them for you.
-
-
-=head2 Setting up your application
-
-Catalyst includes a helper script, C<catalyst.pl>, that will set up a 
-skeleton application for you:
-
-    $ catalyst.pl My::App
-    created "My-App"
-    created "My-App/script"
-    created "My-App/lib"
-    created "My-App/root"
-    created "My-App/t"
-    created "My-App/t/m"
-    created "My-App/t/v"
-    created "My-App/t/c"
-    created "My-App/lib/My/App"
-    created "My-App/lib/My/App/M"
-    created "My-App/lib/My/App/V"
-    created "My-App/lib/My/App/C"
-    created "My-App/lib/My/App.pm"
-    created "My-App/Makefile.PL"
-    created "My-App/README"
-    created "My-App/Changes"
-    created "My-App/t/01app.t"
-    created "My-App/t/02podcoverage.t"
-    created "My-App/script/cgi.pl"
-    created "My-App/script/nph-cgi.pl"
-    created "My-App/script/fcgi.pl"
-    created "My-App/script/server.pl"
-    created "My-App/script/test.pl"
-    created "My-App/script/create.pl"
+The Catalyst framework is a flexible and comprehensive environment for
+quickly building high-functionality web applications.  This tutorial is
+designed to provide a rapid introduction to its basics and its most
+commonly used features while focusing on real-world best practices.
 
-This creates the directory structure shown, populated with skeleton 
-files.
+The tutorial is divided into the following sections:

-You can test out your new application by running the server script that
-catalyst provides:

-=head2 Getting your application invoked
+=back
+
+A tarball of the final application is available at
+C<to_be_compled_in_final_version>.
 
-Catalyst applications are usually run from mod_perl, but can also be
-run as CGI or FastCGI scripts.  Running under mod_perl gives better 
-performance, but for development purposes you may want to run your 
-application as a CGI script, especially as changes to your application 
-code take effect under CGI without having to restart the web server.
+=head1 Detailed Table Of Contents
 
-To run from mod_perl you need to add something like this to your Apache
-configuration file:
+=head2 Part 1: Introduction
+
+=over 4
 
-    <Location /my-app>
-        SetHandler  perl-script
-        PerlHandler My::App
-    </Location>
+=item *
 
-To run as a CGI script you need a wrapper script like:
+VERSIONS AND CONVENTIONS USED IN THIS TUTORIAL
 
-    #!/usr/bin/perl -w
+=item *
 
-    use strict;
-    use lib '/path/to/My/App/lib';
-    use My::App;
+CATALYST INSTALLATION
 
-    My::App->run;
+=item *
 
+DATABASES
 
+=item *
 
-=head2 Examining the generated code
+WHERE TO GET WORKING CODE
 
-The generated application code is quite simple and looks something 
-like this:
+=back
 
-    package My::App;
 
-    use strict;
-    use Catalyst qw/-Debug/;
+=head2 Part 2: Catalyst Application Development Basics
 
-    our $VERSION = '0.01';
+=over 4
 
-    My::App->config(
-    name => 'My::App',
-    root => '/home/andrew/My-App/root',
-    );
+=item *
 
-    __PACKAGE__->setup();
+CREATE A CATALYST PROJECT
 
-    sub default : Private {
-      my ( $self, $c ) = @_;
-      $c->res->output('Congratulations, My::App is on Catalyst!');
-    }
+=item *
 
-    1;
+CREATE A SQLITE DATABASE
 
+=item *
 
-When the C<Catalyst> module is imported by the application code, 
-Catalyst performs the first stage of its initialization.  This includes
-loading the appropriate Engine module for the environment in which the 
-application is running, loading any plugins and ensuring that the 
-calling module (the application module) inherits from C<Catalyst> 
-(which makes the Catalyst methods C<config> and C<setup> available to 
-the application module).
+EDIT THE LIST OF CATALYST PLUGINS
 
-The call to C<config> sets up configuration data for the application.  
-The C<name> and C<root> items are the minimum required, and specify 
-the name of the application and the path to the root directory where 
-documents, images and templates can be found.
+=item *
 
-Catalyst associates I<actions> with URLs and on receiving a request 
-dispatches to the action that matches to request URL.  The call to 
-C<setup> in the code above registers a default action.  With just 
-this action registered the application will respond to all requests 
-with the same message "Congratulations, My::App is on Catalyst!".
+DATABASE ACCESS WITH DBIx::Class
 
-As you see, the default action is defined as a Private action. 
-Most private actions are not directly available from a web url. The
-exceptions are the built-in actions, 'default','begin','end' and
-'auto'. The rest can only be reached by using C<forward>.
 
+=over 4
 
-The call to the C<setup> method also triggers the second stage of 
-Catalyst's initialization process.  In this phase Catalyst searches 
-for any component modules, locating and registering any actions it 
-finds in those modules.
+=item *
 
-Component modules have names prefixed with the application module name,
-followed by C<Model>, C<View> or C<Controller> (or the default short
-forms: C<M>, C<V> or C<C>) followed by the component name, for example:
+Create a DBIC Schema File
 
-    My::App::Controller::ShoppingCart  # long version
-    My::App::C::ShoppingCart           # short version 
+=item *
 
+Create the DBIC ``Result Source'' Files
 
+=item *
 
-=head2 Extending the generated code
+Use Catalyst::Model::DBIC::Schema to Load the Model Class
 
+=back
 
-You can start extending the application by adding new actions:
 
-    sub test1 : Global {
-      my ( $self, $c ) = @_;
-      $c->res->output('In a new test action #1');
-    }
-    sub default : Private {
-      my ( $self, $c ) = @_;
-      $c->res->output('Congratulations, My::App is on Catalyst!');
-    }
+=item *
 
+CREATE A CATALYST CONTROLLER
 
-TODO: explain briefly about plugins, actions and components
+=item *
 
-regex actions passed subexpression matches in $c->req->snippets
-(array ref).
+CATALYST VIEWS
 
 
-=head2 Hooking in to Template Toolkit
+=over 4
 
-One of the first things you will probably want to add to your 
-application is a templating system for generating your output.  
-Catalyst works well with Template Toolkit.  If you are unfamiliar with 
-Template Toolkit then I suggest you look at L<http://tt2.org>, install 
-C<Template>, read the documentation and play around with it, and have 
-a look at the I<Badger Book> (I<Template Toolkit> by Darren 
-Chamberlain, Dave Cross and Andy Wardly, O'Reilly & Associates, 2004).
+=item *
 
-You can create a stub Template Toolkit view component using the create 
-script that Catalyst set up as part of the skeleton application:
+Create a Catalyst View Using TTSite
 
-    $ script/create.pl view TT TT
+=item *
 
-this generates a view component named C<My::App::V::TT>, which you 
-might use by forwarding from your C<end> action:
+Using RenderView for the Default View
 
-    # In My::App or My::App::Controller::SomeController
+=item *
 
-    sub end : Private {
-        my($self, $c) = @_;
-        $c->forward('My::App::V::TT');
-    }
+Globally Customize Every View
 
-The generated TT view component simply subclasses the 
-C<Catalyst::View::TT> class.  It looks like this (with the POD 
-stripped out): 
+=item *
 
-    package My::App::V::TT;
+Create a TT Template Page
 
-    use strict;
-    use base 'Catalyst::View::TT';
+=back
 
-    1;
 
-C<Catalyst::View::TT> initializes a Template Toolkit object with an 
-options hash initialized with built-in default settings followed by 
-the contents of the hash C<<%{__PACKAGE__->config()}>>.  You can
-configure TT more to your needs by adding a C<new> method to the 
-generated TT component:
+=item *
 
-    sub new {
-      my $self = shift;
-      $self->config->{PRE_PROCESS} = 'config/main';
-      $self->config->{WRAPPER}     = 'site/wrapper';
-      return $self->SUPER::new(@_);
-    }
