+
+The `note_taking` member identifies a web app as a note-taking app and defines related information, for example a URL pointing to functionality for taking a new note. This enables operating systems to integrate the app's note taking functionality, for example including a "New note" option in the app's context menu, or providing the app as an option for taking a note in other apps.
+
+### Values
+
+An object, which may contain the following values:
+
+- `new_note_url`
+
+  - : A string representing the URL the developer would prefer the user agent to load when the user wants to take a new note via the web app. This value is a hint, and different implementations may choose to ignore it or provide it as a choice in appropriate places. The `new_note_url` is parsed with the app's manifest URL as its base URL and is ignored if not within the [scope](/en-US/docs/Web/Manifest/scope) of the manifest.
+
