+The default set of tracked hooks is `['activate', 'mount', 'update']`.
+
 The following hooks are available to track: `['activate', 'create', 'unmount', 'mount', 'update']`
 
 Note that when specifying `hooks`, we use the simple verb rather than `before` and `-ed` pairs. For example, `unmount` is correct, while `beforeUnmount` and `unmounted` are incorrect.
