+### Hooks
+
+There are three types of hooks, init hooks, shutdown hooks and error hooks. Init hooks are executed before the task is executed. Shutdown hook is executed after task is executed before application shuts down. Finally error hooks are executed whenever there's an error in the application lifecycle. You can provide multiple hooks for each stage.
