-_Welcome to "Introduction to GitHub"! :wave:_
+_Nicely done! :sunglasses:_
 
-**What is GitHub?**: GitHub is a collaboration platform that uses _[Git](https://docs.github.com/get-started/quickstart/github-glossary#git)_ for versioning. GitHub is a popular place to share and contribute to [open-source](https://docs.github.com/get-started/quickstart/github-glossary#open-source) software.

+You successfully created a pull request. You can now merge your pull request.
 
-**What is a repository?**: A _[repository](https://docs.github.com/get-started/quickstart/github-glossary#repository)_ is a project containing files and folders. A repository tracks versions of files and folders. For more information, see "[About repositories](https://docs.github.com/en/repositories/creating-and-managing-repositories/about-repositories)" from GitHub Docs.
+**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)."
 
-**What is a branch?**: A _[branch](https://docs.github.com/en/get-started/quickstart/github-glossary#branch)_ is a parallel version of your repository. By default, your repository has one branch named `main` and it is considered to be the definitive branch. Creating additional branches allows you to copy the `main` branch of your repository and safely make any changes without disrupting the main project. Many people use branches to work on specific features without affecting any other parts of the project.
+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.
 
-Branches allow you to separate your work from the `main` branch. In other words, everyone's work is safe while you contribute. For more information, see "[About branches](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-branches)".

-**What is a profile README?**: A _[profile README](https://docs.github.com/account-and-profile/setting-up-and-managing-your-github-profile/customizing-your-profile/managing-your-profile-readme)_ is essentially an "About me" section on your GitHub profile where you can share information about yourself with the community on GitHub.com. GitHub shows your profile README at the top of your profile page. For more information, see "[Managing your profile README](https://docs.github.com/en/account-and-profile/setting-up-and-managing-your-github-profile/customizing-your-profile/managing-your-profile-readme)".
