-## Step 2: Commit a file
+## Step 4: Merge your pull request
 
-_You created a branch! :tada:_
+_Nicely done! :sunglasses:_
 
-Creating a branch allows you to edit your project without changing the `main` branch. Now that you have a branch, it’s time to create a file and make your first commit!
+You successfully created a pull request. You can now merge your pull request.
 
-**What is a commit?**: A _[commit](https://docs.github.com/pull-requests/committing-changes-to-your-project/creating-and-editing-commits/about-commits)_ is a set of changes to the files and folders in your project. A commit exists in a branch. For more information, see "[About commits](https://docs.github.com/en/pull-requests/committing-changes-to-your-project/creating-and-editing-commits/about-commits)".
+**What is a merge?**: A _[merge](https://docs.github.com/en/get-started/quickstart/github-glossary#merge)_ adds the changes in your pull request and branch into the `main` branch. For more information about merges, see "[Merging a pull request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/incorporating-changes-from-a-pull-request/merging-a-pull-request)."
 
-### :keyboard: Activity: Your first commit
+As noted in the previous step, you may have seen evidence of GitHub Actions running which automatically progresses your instructions to the next step. You'll have to wait for it to finish before you can merge your pull request. It will be ready when the merge pull request button is green.
 
-The following steps will guide you through the process of committing a change on GitHub. A commit records changes in renaming, changing content within, creating a new file, and any other changes made to your project. For this exercise, committing a change requires first adding a new file to your new branch.

-5. Click **Commit changes...** in the upper right corner above the contents box. For commits, you can enter a short commit message that describes what changes you made. This message helps others know what's included in your commit. GitHub offers a simple default message, but let's change it slightly for practice. First, enter `Add PROFILE.md` in the first text-entry field titled "Commit message".
