-## Step 4: Create a blog post
+## Step 5: Merge your pull request
 
-_Your home page is looking great! :cowboy_hat_face:_
+_Nice work, friend :heart:! People will be reading your blog in no time!_
 
-GitHub Pages uses Jekyll. In Jekyll, we can create a blog by using specially named files and frontmatter. The files must be named `_posts/YYYY-MM-DD-title.md`. You must also include `title` and `date` in your frontmatter.
+You can now [merge](https://docs.github.com/en/get-started/quickstart/github-glossary#merge) your pull request!
 
-**What is _frontmatter_?**: The syntax Jekyll files use is called YAML frontmatter. It goes at the top of your file and looks something like this:
+### :keyboard: Activity: Merge your changes
 
-```yml
----
-title: "Welcome to my blog"
-date: 2019-01-20
----
-```
-
-For more information about configuring front matter, see the [Jekyll frontmatter documentation](https://jekyllrb.com/docs/frontmatter/).
-
-### :keyboard: Activity: Create a blog post
-
-1. Browse to the `my-pages` branch.
-1. Click the `Add file` dropdown menu and then on `Create new file`.
-1. Name the file `_posts/YYYY-MM-DD-title.md`.
-1. Replace the `YYYY-MM-DD` with today's date, and change the `title` of your first blog post if you'd like.
-   > If you do edit the title, make sure there are hyphens between your words.
-   > If your blog post date doesn't follow the correct date convention, you'll receive an error and your site won't build. For more information, see "[Page build failed: Invalid post date](https://docs.github.com/en/pages/setting-up-a-github-pages-site-with-jekyll/troubleshooting-jekyll-build-errors-for-github-pages-sites)".
-1. Type the following content at the top of your blog post:
-   ```yaml
-   ---
-   title: "YOUR-TITLE"
-   date: YYYY-MM-DD
-   ---
-   ```
-1. Replace `YOUR-TITLE` with the title for your blog post.
-1. Replace `YYYY-MM-DD` with today's date.
-1. Type a quick draft of your blog post. Remember, you can always edit it later.
-1. Commit your changes to your branch.
+1. Merge your changes from `my-pages` into `main`. If you created the pull request in step 2, just open that PR and click on **Merge pull request**. If you did not create the pull request earlier, you can do it now by following the instructions in [step 2](/.github/steps/2-configure-your-site.md).
+1. (optional) Delete the branch `my-pages`.
 1. Wait about 20 seconds then refresh this page (the one you're following instructions from). [GitHub Actions](https://docs.github.com/en/actions) will automatically update to the next step.
