-  __PACKAGE__->load_classes(qw/ Album Artist /);
+  # load My::Schema::Result::* and their resultset classes
+  __PACKAGE__->load_namespaces();
 
-Or load classes by namespace:
+By default this loads all the Result (Row) classes in the
+My::Schema::Result:: namespace, and also any resultset classes in the
+My::Schema::ResultSet:: namespace (if missing, the resultsets are
+defaulted to be DBIx::Class::ResultSet objects). You can change the
+result and resultset namespaces by using options to the
+L<DBIx::Class::Schema/load_namespaces> call.

-    {
-      'My::Schema' => [qw/ Album Artist /],
-      'My::OtherSchema' => [qw/ LinerNotes /]
-    }
-  );
+It is also possible to do the same things manually by calling
+C<load_classes> for the Row classes and defining in those classes any
+required resultset classes.
 
-Or let your schema class load all classes in its namespace automatically:
-
-   # load My::Schema::*
-  __PACKAGE__->load_classes();
-
 Next, create each of the classes you want to load as specified above:
 
-  package My::Schema::Album;
+  package My::Schema::Result::Album;
   use base qw/DBIx::Class/;
 
 Load any components required by each class with the load_components() method.
