   you and your team can collaborate on new features faster
 - Updates the deployment and the comment whenever new commits are pushed to
   the pull request
+- Can optionally include a QR code in the preview comment for easy mobile access
 - Cleans up after itself — removes deployed previews when the pull
   request is closed
 - Can be configured to override any of these behaviours
@@ -102,6 +103,7 @@ Input parameter | Description
 `pages-base-url` | Base URL to use when providing a link to the preview site. <br><br> Default: The pull request's target repository's default GitHub Pages URL (e.g. `rossjrw.github.io/pr-preview-action/`)
 `pages-base-path` | Path that GitHub Pages is being served from, as configured in your repository settings, e.g. `docs/`. When generating the preview URL path, this is removed from the beginning of the file path. <br><br> Default: `.` (repository root)
 `comment` <br> (boolean) | Whether to leave a [sticky comment](https://github.com/marocchino/sticky-pull-request-comment) on the PR after the preview is built.<br> The comment may be added before the preview finishes deploying. <br><br> Default: `true`
+`qr-code` <br> (boolean) | Whether to include a QR code in the preview comment for easy mobile access. The QR code links to the preview URL. <br><br> Default: `false`
 `token` | Authentication token for the preview deployment. <br> The default value works for non-fork pull requests to the same repository. For anything else, you will need a [Personal Access Token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token) with permission to access it, and [store it as a secret](https://docs.github.com/en/actions/security-guides/using-secrets-in-github-actions) in your repository. E.g. you might name that secret 'PREVIEW_TOKEN' and use it with `token: ${{ secrets.PREVIEW_TOKEN }}`. <br><br> Default: `${{ github.token }}`, which gives the action permission to deploy to the current repository.
 `action` <br> (enum) | Determines what this action will do when it is executed. Supported values: <br><br> <ul><li>`deploy` - create and deploy the preview, overwriting any existing preview in that location.</li><li>`remove` - remove the preview.</li><li>`auto` - determine whether to deploy or remove the preview based on [the emitted event](https://docs.github.com/en/developers/webhooks-and-events/webhooks/webhook-events-and-payloads#pull_request). If the event is `pull_request`, it will deploy the preview when the event type is `opened`, `reopened` and `synchronize`, and remove it on `closed` events. Does not do anything for other events or event types, even if you explicitly instruct the workflow to run on them.</li><li>`none` and all other values: does not do anything.</li></ul> Default: `auto`
