+## Step 4: Merge your workflow file
 
-Automation is key for streamlining your work processes, and [GitHub Actions](https://docs.github.com/actions) is the best way to supercharge your workflow.
+_You're now able to write and run an Actions workflow! :sparkles:_
 
-- **Who is this for**: Developers, DevOps engineers, students, managers, teams, GitHub users.
-- **What you'll learn**: How to create workflow files, trigger workflows, and find workflow logs.
-- **What you'll build**: An Actions workflow that will check emoji shortcode references in Markdown files.
-- **Prerequisites**: In this course you will work with issues and pull requests, as well as edit files. We recommend you take the [Introduction to GitHub](https://github.com/skills/introduction-to-github) course first.
-- **How long**: This course can be finished in less than two hours.
+Merge your changes so the action will be a part of the `main` branch.
 
-In this course, you will:
+### :keyboard: Activity: Merge your workflow file

-2. In the new tab, most of the prompts will automatically fill in for you.
-   - For owner, choose your personal account or an organization to host the repository.

-   - Scroll down and click the **Create repository** button at the bottom of the form.
-3. After your new repository is created, wait about 20 seconds, then refresh the page. Follow the step-by-step instructions in the new repository's README.
+1. In your repo, click on the **Pull requests** tab.
+1. Click on the pull request you created in step 1.
+1. Click **Merge pull request**, then click **Confirm merge**.
+1. Optionally, click **Delete branch** to delete your `welcome-workflow` branch.
+1. Wait about 20 seconds for actions to run, then refresh this page (the one you're following instructions from) and an action will automatically close this step and open the next one.
