Of course the Plugin from wpml.org has to be installed, the file "wpml-integration.php" from docs/theme-integration has to be copied into your theme-directory and the call include "wpml-integration.php"; has to be copied to your functions.php. After that, you can simply place <?php> somewhere in your theme.
