An `updatefound` event using the `[Event][3]` interface is dispatched on `[ServiceWorkerContainer][2]` object (See step 4 of the [_Installation algorithm][4]) when the associated Service Worker [registration][5] for the document enters the [installation process][6] such that `navigator.serviceWorker.installing` becomes the new [installing worker][7].
