-For security reasons, GitHub Pages build runs on `safe` mode, which restricts us from using plugins to generate additional page files. Therefore, we can use **GitHub Actions** to build the site, store the built site files on a new branch, and use that branch as the source of the GitHub Pages service.
+Ensure your Jekyll site has the file `.github/workflows/pages-deploy.yml`{: .filepath}. Otherwise, create a new one and fill in the contents of the [sample file][workflow], and the value of the `on.push.branches` should be the same as your repo's default branch name. And then rename your repository to `<GH_USERNAME>.github.io` on GitHub.

-- Furthermore, if you have committed `Gemfile.lock`{: .filepath} to the repo, and your runtime system is not Linux, don't forget to update the platform list in the lock file:
-
-  ```console
-  $ bundle lock --add-platform x86_64-linux
-  ```
-
-After the above steps, rename your repository to `<GH_USERNAME>.github.io` on GitHub.
 
 Now publish your Jekyll site:
 
 1. Browse to your repository on GitHub. Select the tab _Settings_, then click _Pages_ in the left navigation bar. Then, in the **Source** section (under _Build and deployment_), select [**GitHub Actions**][pages-workflow-src] from the dropdown menu.
