 ## Generating Release notes
 - Release notes for DevTools are hosted on the flutter website (see [archive](https://docs.flutter.dev/development/tools/devtools/release-notes)).
 - To add release notes for the latest release, create a PR with the appropriate changes for your release.
-    - To generate the release notes run:
-
-        `dart tool/release_note_helper.dart markdown -f tool/release_notes/release_notes.json`
+    - The [NEXT_RELEASE_NOTES.md](../../../../../../tool/release_notes/NEXT_RELEASE_NOTES.md) file contains the running release notes for the current version.
+    - see example [PR](https://github.com/flutter/website/pull/6791) for an idea of how to add those to the Flutter website.
 - Test these changes locally before creating the PR.
     - See [README.md](https://github.com/flutter/website/blob/main/README.md)
 for getting setup to run the Flutter website locally.
