=head1 DESCRIPTION
Allows you to call your L<DBIx::Class::Schema> methods directly on the Model
-instance, and passes config options to the C<Schema> attributes at C<BUILD>
-time.
+instance, and passes config options to your L<DBIx::Class::Schema> and
+L<DBIx::Class::ResultSet> attributes at C<BUILD> time.
-Methods and attributes local to your C<Model> take precedence over C<Schema>
-methods and attributes.
+Methods and attributes local to your C<Model> take precedence over
+L<DBIx::Class::Schema> or L<DBIx::Class::ResultSet> methods and attributes.
+
+=head1 CREATING SCHEMA CONFIG ATTRIBUTES
+
+To create attributes in your C<Schema.pm>, use either Moose or
+L<Class::Accessor::Grouped>, which is inherited from by all L<DBIx::Class>
+classes automatically. E.g.:
+
+ __PACKAGE__->mk_group_accessors(simple => qw/
+ config_key1
+ config_key2
+ ...
+ /);
+
+Or with L<Moose>:
+
+ use Moose;
+ has config_key1 => (is => 'rw', default => 'default_value');
+
+This code can be added after the md5sum on L<DBIx::Class::Schema::Loader>
+generated schemas.
+
+At app startup, any non-local options will be passed to these accessors, and can
+be accessed as usual via C<< $schema->config_key1 >>.
+
+These config values go into your C<Model::DB> block, along with normal config
+values.
+
+=head1 CREATING RESULTSET CONFIG ATTRIBUTES
+
+You can create classdata on L<DBIx::Class::ResultSet> classes to hold values
+from L<Catalyst> config.
+
+The code for this looks something like this:
+
+ package MySchema::ResultSet::Foo;
+
+ use base 'DBIx::Class::ResultSet';
+
+ __PACKAGE__->mk_group_accessors(inherited => qw/
+ rs_config_key1
+ rs_config_key2
+ ...
+ /);
+ __PACKAGE__->rs_config_key1('default_value');
+
+Or, if you prefer L<Moose>:
+
+ package MySchema::ResultSet::Foo;
+
+ use Moose;
+ use MooseX::NonMoose;
+ use MooseX::ClassAttribute;
+ extends 'DBIx::Class::ResultSet';
+
+ class_has rs_config_key1 => (is => 'rw', default => 'default_value');
+
+In your catalyst config, use the generated Model name as the config key, e.g.:
+
+ <Model::DB::Users>
+ strict_passwords 1
+ </Model::DB::Users>
