+## Step 1: Create a pull request
+
+_Welcome to "Managing Merge Conflicts"! :wave:_
+
+**What is a _merge conflict_?**: A **merge conflict** occurs when changes are made to the same part of the same file on two different branches. You usually find out about conflicts in a pull request so let's start by creating one.
+
+### :keyboard: Activity: Create a pull request
+
+1. Open a new browser tab, and work on the steps in your second tab while you read the instructions in this tab.
+1. We made a small change to a file in the repository in the `my-resume` branch.
+1. [Create a pull request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request) setting `my-resume` as the head branch and `main` as the base branch. You can enter `Resolving merge conflicts` for the pull request title and body.
+1. 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.

+## Step 2: Resolve a merge conflict
+
+_Good start! Now let's look deeper at a merge conflict! :mag:_
+
+This can be intimidating, but have no fear, Git is smart when it comes to merging! Git only needs a human to decide how to [resolve the conflict](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/addressing-merge-conflicts/resolving-a-merge-conflict-using-the-command-line). Sometimes, the best way to resolve a merge conflict is to add content that's from both branches, or even something that isn't on either! This is why Git needs a human to look at the code and make the proper fixes.
+
+### :keyboard: Activity: Resolve a merge conflict
+
+1. Open the pull request that you just created, we created a conflict for you. Have no fear!
+1. At the bottom of the page, under "This branch has conflicts that must be resolved", click the **Resolve conflicts** button.
+1. Look for the highlighted sections that begins with `<<<<<<< my-resume` and ends with `>>>>>>> main`. These markers are added by Git to show you the content that is in conflict.
+1. Remove the changes made on the main branch by deleting all of the content below the `=======` and above `>>>>>>> main`.
+1. Next, remove the merge conflict markers by deleting the following lines:
+   ```
+   <<<<<<< my-resume
+   =======
+   >>>>>>> main
+   ```
+1. With the merge conflict markers removed, click **Mark as resolved**.
+1. Finally, click **Commit merge**.
+1. 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.

+
+## Step 3: Create your own conflict
+
+_Good job! You've solved a merge conflict! :tada:_
+
+Resolving a conflict doesn't automatically merge the pull request in GitHub. Instead, it stores the resolution of the conflict in a merge commit and allows you and your team to keep working. To resolve a conflict, GitHub performs what is known as a _reverse merge_. This means that the changes from the `main` branch were merged into your `my-resume` branch. With a reverse merge, only the `my-resume` branch is updated. This allows you to test the resolved changes on your branch before you merge it into `main`.
+
+Now, let's get a little evil. (It's for educational purposes!)
+
+### :keyboard: Activity: Create your own conflict
+
+We went ahead and added a new file called `references.md` and pushed that change to `main`, without updating your `my-resume` branch.
+
+1. Browse to the `my-resume` branch.
+1. Click the `Add file` dropdown menu and then on `Create new file`.
+1. Create a file named `references.md`.
+1. Enter some text that conflicts with what we added for `references.md` in the `main` branch.
+1. Scroll to the bottom of the page and enter a commit message for your change.
+1. Click the **Commit new file** button, making sure the "Commit directly to the `my-resume` branch" option is selected.
+1. 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.

+
+You can now [merge](https://docs.github.com/en/get-started/quickstart/github-glossary#merge) your pull request!
+
+### :keyboard: Activity: Merge your pull request
+
+1. First, resolve any remaining conflicts in your pull request.
+   > Look back at step one if you need help.
+1. Click **Merge pull request**.
