 Hooks associated to `cleanup` events are triggered after each release is processed.
 
-Hooks associated to `presync` events are triggered before each release is applied to the remote cluster. This is the ideal event to execute any commands that may mutate the cluster state as it will not be run for read-only operations like `lint`, `diff` or `template`.
