=head1 DESCRIPTION
Oof (Oversimplified order form) is a very simple ecommerce website.
-As of this moment it is incomplete (although functional), hence the
-version number.
+It is the code behind L<https://ledparts4you.uk.to>.
+
+This version is reasonably functional, yet not very reusable, hence
+the version number.
