-DBIx::Class::PK::Auto - Automatic Primary Key class
+DBIx::Class::PK::Auto - Automatic primary key class
=head1 SYNOPSIS
+use base 'DBIx::Class::Core';
+__PACKAGE__->set_primary_key('id');
+
=head1 DESCRIPTION
-This class overrides the insert method to get automatically
-incremented primary keys.
+This class overrides the insert method to get automatically incremented primary
+keys.
+
+PK::Auto is now part of Core.
+
+See L<DBIx::Class::Manual::Component> for details of component interactions.
+
+=head1 LOGIC
+
+C<PK::Auto> does this by letting the database assign the primary key field and
+fetching the assigned value afterwards.
=head1 METHODS
-=over 4
+=head2 insert
+
+The code that was handled here is now in Row for efficiency.
-=item insert
+=head2 sequence
-Overrides insert so that it will get the value of autoincremented
-primary keys.
+Manually define the correct sequence for your table, to avoid the overhead
+associated with looking up the sequence automatically.
