-## ClassmapTask
+You must initialize an instance of your Zf2 application through **ZfTask** before using any of the remaining Tasks.
 
-Generate a classmap for the directory `foo/library` (and its subdirectories), save it at `foo/autoload_classmap.php`.
+## ZfTask
+
+Bootstrap the ZF2 application using the file `foo/bootstrap.php`. The bootstrap file must return an instance of `Zend\Mvc\Application`.
