+#### Posting format diff as Github review suggestions
+
+The following setup can be used to post any formatting changes as review comments on Github
+pull requests. This passses `format_files: true` to tell Runic to format the files and leave
+the diff behind, and then uses
+[reviewdog/action-suggester](https://github.com/reviewdog/action-suggester) to post the diff
+as comments. You need to configure `continue-on-error` for `runic-action` and then configure
+`reviewdog/action-suggester` (or whatever other follow up action you are using) to fail
+instead. For `reviewdog/action-suggester` this is done by setting `fail_level` as in the
+example below.
+
+```yaml

+    branches:

+        if: github.event_name == 'pull_request'
