 ----------
 * Annotation classes must be annotated with @Annotation 
   (see the validator constraints for examples)
-* Annotations are not using the PHP autoloading but their own mechanism. This allows much more control
-  about possible failure states. To make your code work you have to add the following lines to your
-  autoload.php:
-
-    AnnotationRegistry::registerLoader(function($class) use ($loader) {
-        $loader->loadClass($class);
-        return class_exists($class, false);
-    });
-    AnnotationRegistry::registerFile(
-        __DIR__.'/../vendor/doctrine/lib/Doctrine/ORM/Mapping/Driver/DoctrineAnnotations.php'
-    );
-
-  The `$loader` variable is an instance of the UniversalClassLoader. Additionally you might have to adjust
-  the ORM path to the DoctrineAnnotations.php. If you are not using the UniversalClassLoader see the
-  [Doctrine Annotations documentation](http://www.doctrine-project.org/docs/common/2.1/en/reference/annotations.html)
