+#### Deregistration of synchronous customization hooks
+
+The object returned by `registerHooks()` has a `deregister()` method that can be
+used to remove the hooks from the chain. Once `deregister()` is called, the hooks
+will no longer be invoked during module resolution or loading.
+
+This is currently only available for synchronous hooks registered via `registerHooks()`, not for asynchronous
+hooks registered via `module.register()`.
