+Manual creation of a DBIx::Class::Schema and a Catalyst::Model::DBIC::Schema:
+
+=over
+
+=item 1.
+
+Create the DBIx:Class schema in MyApp/Schema/FilmDB.pm:
+
+ package MyApp::Schema::FilmDB;
+ use base qw/DBIx::Class::Schema/;
+
+ __PACKAGE__->load_classes(qw/Actor Role/);
+
+=item 2.
+
+Create some classes for the tables in the database, for example an
+Actor in MyApp/Schema/FilmDB/Actor.pm:
+
+ package MyApp::Schema::FilmDB::Actor;
+ use base qw/DBIx::Class/
+
+ __PACKAGE__->load_components(qw/Core/);
+ __PACKAGE__->table('actor');
+
+ ...
+
+and a Role in MyApp/Schema/Role.pm:
+
+ package MyApp::Schema::FilmDB::Role;
+ use base qw/DBIx::Class/
+
+ __PACKAGE__->load_components(qw/Core/);
+ __PACKAGE__->table('role');
+
+ ...
+
+Notice that the schema is in MyApp::Schema, not in MyApp::Model. This way it's
+usable as a standalone module and you can test/run it without Catalyst.
+
+=item 3.
+
+To expose it to Catalyst as a model, you should create a DBIC Model in
+MyApp/Model/FilmDB.pm:
+
+ package MyApp::Model::FilmDB;
+ use base qw/Catalyst::Model::DBIC::Schema/;
+
+ __PACKAGE__->config(
+ schema_class => 'MyApp::Schema::FilmDB',
+ connect_info => [
+ "DBI:...",
+ "username",
+ "password",
+ {AutoCommit => 1}
+ ]
+ );
+
+See below for a full list of the possible config parameters.
+
+=back
+
+Now you have a working Model, accessing your separate DBIC Schema. Which can
+be used/accessed in the normal Catalyst manner, via $c->model():
+
+ my $actor = $c->model('FilmDB::Actor')->find(1);
+
+You can also use it to set up DBIC authentication with
+Authentication::Store::DBIC in MyApp.pm:
+
+ package MyApp;
+
+ use Catalyst qw/... Authentication::Store::DBIC/;
+
+ ...
+
+ __PACKAGE__->config->{authentication}{dbic} = {
+ user_class => 'FilmDB::Actor',
+ user_field => 'name',
+ password_field => 'password'
+ }
+
+C<< $c->model() >> returns a L<DBIx::Class::ResultSet> for the source name
+parameter passed. To find out more about which methods can be called on a
+ResultSet, or how to add your own methods to it, please see the ResultSet
+documentation in the L<DBIx::Class> distribution.
+
+Some examples are given below:
+
+ # to access schema methods directly:
+ $c->model('FilmDB')->schema->source(...);
+
+ # to access the source object, resultset, and class:
+ $c->model('FilmDB')->source(...);
+ $c->model('FilmDB')->resultset(...);
+ $c->model('FilmDB')->class(...);
+
+ # For resultsets, there's an even quicker shortcut:
+ $c->model('FilmDB::Actor')
+ # is the same as $c->model('FilmDB')->resultset('Actor')
+
+ # To get the composed schema for making new connections:
+ my $newconn = $c->model('FilmDB')->composed_schema->connect(...);
+
+ # Or the same thing via a convenience shortcut:
+ my $newconn = $c->model('FilmDB')->connect(...);
+
+ # or, if your schema works on different storage drivers:
+ my $newconn = $c->model('FilmDB')->composed_schema->clone();
+ $newconn->storage_type('::LDAP');
+ $newconn->connection(...);
+
+ # and again, a convenience shortcut
+ my $newconn = $c->model('FilmDB')->clone();
+ $newconn->storage_type('::LDAP');
+ $newconn->connection(...);
=head1 DESCRIPTION
This is a Catalyst Model for L<DBIx::Class::Schema>-based Models. See
-the documentation for L<Catalyst::Helper::Model::DBIC::Schema> and
-L<Catalyst::Helper::Model::DBIC::SchemaLoader> for information
-on generating these Models via Helper scripts. The latter of the two
-will also generated a L<DBIx::Class::Schema::Loader>-based Schema class
-for you.
+the documentation for L<Catalyst::Helper::Model::DBIC::Schema> for
+information on generating these Models via Helper scripts.
=head1 CONFIG PARAMETERS
=item schema_class
This is the classname of your L<DBIx::Class::Schema> Schema. It needs
-to be findable in C<@INC>, but it does not need to be underneath
-C<Catalyst::Model::>. This parameter is required.
+to be findable in C<@INC>, but it does not need to be inside the
+C<Catalyst::Model::> namespace. This parameter is required.
=item connect_info
C<storage_type> (see your storage type documentation for more details).
This is not required if C<schema_class> already has connection information
-defined in itself (which would be the case for a Schema defined by
-L<DBIx::Class::Schema::Loader>, for instance).
+defined inside itself (which isn't highly recommended, but can be done)

C<storage_type> in L<DBIx::Class> at the time of this writing, the
