+=head1 QUICKSTART
+
+If you're using Class::DBI, replacing
+
+use base qw/Class::DBI/;
+
+with
+
+use base qw/DBIx::Class/;
+__PACKAGE__->load_components(qw/CDBICompat Core/);
+
+will probably get you started.
+
+If you're using AUTO_INCREMENT for your primary columns, you'll also want
+yo load the approriate PK::Auto subclass - e.g.
+
+__PACKAGE__->load_components(qw/CDBICompat PK::Auto::SQLite Core/);
+
+(with is what ::Test::SQLite does to present the Class::DBI::Test::SQLite
+interface)
+
+If you fancy playing around with DBIx::Class from scratch, then read the docs
+for ::Table and ::Relationship,
+
+use base qw/DBIx::Class/;
+__PACKAGE__->load_components(qw/Core/);
+
+and have a look at t/lib/DBICTest.pm for a brief example.
