-## Step 2: Commit a file
+## Step 3: Open a pull request
 
-_You created a branch! :tada:_
+_Nice work making that commit! :sparkles:_
 
-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!
+Now that you have made a change to the project and created a commit, it’s time to share your proposed change through a 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 pull request?**: Collaboration happens on a _[pull request](https://docs.github.com/en/get-started/quickstart/github-glossary#pull-request)_. The pull request shows the changes in your branch to other people and allows people to accept, reject, or suggest additional changes to your branch. In a side by side comparison, this pull request is going to keep the changes you just made on your branch and propose applying them to the `main` project branch. For more information about pull requests, see "[About pull requests](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-pull-requests)".

-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.
+You may have noticed after your commit that a message displayed indicating your recent push to your branch and providing a button that says **Compare & pull request**.
 
-> [!NOTE]
-> `.md` is a file extension that creates a Markdown file. You can learn more about Markdown by visiting "[Basic writing and formatting syntax](https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax)" in our docs or by taking the "[Communicating using Markdown](https://github.com/skills/communicate-using-markdown)" Skills course.

+1. Click on the **Pull requests** tab in the header menu of your repository.
+2. Click **New pull request**.
+3. In the **base:** dropdown, make sure **main** is selected.
+4. Select the **compare:** dropdown, and click `my-first-branch`.

-   ```
-   Welcome to my GitHub profile!
-   ```
+5. Click **Create pull request**.
+6. Enter a title for your pull request. By default, the title will automatically be the name of your branch. For this exercise, let's edit the field to say `Add my first file`.
+7. The next field helps you provide a description of the changes you made. Here, you can add a description of what you’ve accomplished so far. As a reminder, you have: created a new branch, created a file, and made a commit.

-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".
+8. Click **Create pull request**. You will automatically be navigated to your new pull request.
+9. 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.
