=head1 NAME
-DBIx::Class::PK::Auto - Automatic Primary Key class
+DBIx::Class::PK::Auto - Automatic primary key class
=head1 SYNOPSIS
+ # In your table classes (replace PK::Auto::SQLite with your database)
+ __PACKAGE__->load_components(qw/PK::Auto::SQLite 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.
+
+You don't want to be using this directly - instead load the appropriate one for
+your database, e.g. C<PK::Auto::SQLite>, in your table classes:
+
+ __PACKAGE__->load_components(qw/PK::Auto::SQLite Core/);
+
+Note that C<PK::Auto::SQLite> is specified as the leftmost argument.
+
+Alternatively, you can load the components separately:
-You don't want to be using this directly - instead load the appropriate
-one for your database, e.g. PK::Auto::SQLite
+ __PACKAGE__->load_components(qw/Core/);
+ __PACKAGE__->load_components(qw/PK::Auto::SQLite/);
+
+This can be used, for example, if you have different databases and need to
+determine the appropriate C<PK::Auto> class at runtime.
+
+=head1 LOGIC
+
+C<PK::Auto> does this by letting the database assign the primary key field and
+fetching the assigned value afterwards.
=head1 METHODS
=head2 insert
-Overrides insert so that it will get the value of autoincremented
-primary keys.
+Overrides C<insert> so that it will get the value of autoincremented primary
+keys.
