-**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)."
+Here's a recap of your accomplishments:
 
-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.
+- You learned about GitHub, repositories, branches, commits, and pull requests.
+- You created a branch, a commit, and a pull request.
+- You merged a pull request.
+- You made your first contribution! :tada:

-### :keyboard: Activity: Merge the pull request
+If you'd like to make a profile README, use the quickstart instructions below or follow the instructions in the [Managing your profile README](https://docs.github.com/account-and-profile/setting-up-and-managing-your-github-profile/customizing-your-profile/managing-your-profile-readme) article.
 
-1. Click **Merge pull request**.
-2. Click **Confirm merge**.
-3. Once your branch has been merged, you don't need it anymore. To delete this branch, click **Delete branch**.
+1. Make a new public repository with a name that matches your GitHub username.
+2. Create a file named `README.md` in its root. The "root" means not inside any folder in your repository.
+3. Edit the contents of the `README.md` file.
+4. If you created a new branch for your file, open and merge a pull request on your branch.
+5. Lastly, we'd love to hear what you thought of this course [in our discussion board](https://github.com/orgs/skills/discussions/categories/introduction-to-github).
