 The above snippet set's up a `Harvester` instance with Consul and Redis seed and monitor.
 
-## Notification support
-
-In order to be able to monitor the changes in the configuration we provide a way to notify when a change is happening via the builder.
-
-```go
-    h, err := harvester.New(&cfg).WithNotification(chNotify).Create()
-    ...
-```
-
 ## Consul
 
 Consul has support for versioning (`ModifyIndex`) which allows us to change the value only if the version is higher than the one currently.
