 Adding Your Own Service Worker
 =====
-By default, the service worker implemented by this app is empty.  To add service worker functionality, you'll want to create a `serviceworker.js` or similarly named file, and then point at it using the PWA_SERVICE_WORKER_PATH variable.
+To add service worker functionality, you'll want to create a `serviceworker.js` or similarly named template in a template directory, and then point at it using the PWA_SERVICE_WORKER_PATH variable (PWA_APP_FETCH_URL is passed through).
 
 ```python
 PWA_SERVICE_WORKER_PATH = os.path.join(BASE_DIR, 'my_app', 'serviceworker.js')
 
 ```
 
+The offline view
+=====
+By default, the offline view is implemented in `templates/offline.html`
+You can overwrite it in a template directory if you continue using the default `serviceworker.js`.
