 A GitHub Action to push a website built by [Retype](https://retype.com/) in a previous [`action-build`](https://github.com/retypeapp/action-build) step back to the GitHub repo where it can then be hosted by [GitHub Pages](https://docs.github.com/en/github/working-with-github-pages/getting-started-with-github-pages).

-1. Target a `branch`, or
-2. Target a `directory` in the repo
-3. Configure whether a new branch should be created if it already exists (`update-branch`)

+4. Configure whether a new branch should be created if it already exists (`update-branch`, branch mode)
+5. Configure a GitHub API access token to allow the action to make a Pull Request (`github-token`, branch mode)
 
 ## Prerequisites
 
 This action requires the output of the [retypeapp/action-build](https://github.com/retypeapp/action-build) in a previous step of the workflow.
 
+If you are using the new GitHub Pages publishing model (Pages **Source: GitHub Actions**), you must enable it in your repo first:
+
+- **Settings → Pages → Build and deployment → Source: GitHub Actions**
+
 Please see [Getting Started with GitHub Pages](https://docs.github.com/en/github/working-with-github-pages/getting-started-with-github-pages) for details on how to configure GitHub Pages.
 
 ## Usage
 
-The following `retype.yaml` file demonstrates a typical scenario where the action will trigger Retype to build when changes are pushed to the repo. The fresh Retype powered website is then pushed to a `retype` branch which has been setup in the repo settings to host with GitHub Pages.

+### Publish using GitHub Pages Source: GitHub Actions
+
+If your repository is configured with **Pages Source: GitHub Actions**, you can deploy without pushing generated files to a branch.
+
+Key differences vs branch publishing:
+
+- Your workflow must grant `pages: write` and `id-token: write` permissions.
+- This action will upload a Pages artifact and then deploy it using the official GitHub Pages actions.
