+## Step 2: Add a job to your workflow file
 
-Automation is key for streamlining your work processes, and [GitHub Actions](https://docs.github.com/actions) is the best way to supercharge your workflow.
+_Nice work! :tada: You added a workflow file!_
 
-- **Who is this for**: Developers, DevOps engineers, students, managers, teams, GitHub users.
-- **What you'll learn**: How to create workflow files, trigger workflows, and find workflow logs.
-- **What you'll build**: An Actions workflow that will check emoji shortcode references in Markdown files.
-- **Prerequisites**: In this course you will work with issues and pull requests, as well as edit files. We recommend you take the [Introduction to GitHub](https://github.com/skills/introduction-to-github) course first.
-- **How long**: This course can be finished in less than two hours.
+Here's what it means:
 
-In this course, you will:
+- `name: Post welcome comment` gives your workflow a name. This name appears on any pull request or in the Actions tab of your repository.
+- `on: pull_request: types: [opened]` indicates that your workflow will execute anytime a pull request opens in your repository.
+- `permissions` assigns the workflow permissions to operate on the repository
+- `pull-requests: write` gives the workflow permission to write to pull requests. This is needed to create the welcome comment.
 
-1. Create a workflow
-2. Add a job
-3. Add actions
-4. Merge your pull request
-5. See the action run
+Next, we need to specify jobs to run.
 
-### How to start this course
+**What is a _job_?**: A job is a set of steps in a workflow that execute on the same runner (a runner is a server that runs your workflows when triggered). Workflows have jobs, and jobs have steps. Steps are executed in order and are dependent on each other. We'll add steps in the next step of this exercise. To read more about jobs, see "[Jobs](https://docs.github.com/en/actions/learn-github-actions/understanding-github-actions#jobs)".
 
-<!-- For start course, run in JavaScript:
-'https://github.com/new?' + new URLSearchParams({
-  template_owner: 'skills',
-  template_name: 'hello-github-actions',
-  owner: '@me',
-  name: 'skills-hello-github-actions',
-  description: 'My clone repository',
-  visibility: 'public',
-}).toString()
--->
+In this step of our exercise, we will add a "build" job. We will specify `ubuntu-latest` as the fastest and cheapest job runner available. If you want to read more about why we'll use that runner, see the code explanation for the line `runs-on: ubuntu-latest` in the "[Understanding the workflow file](https://docs.github.com/en/actions/learn-github-actions/understanding-github-actions#understanding-the-workflow-file)" article.

+### :keyboard: Activity: Add a job to your workflow file
 
-1. Right-click **Start course** and open the link in a new tab.
-2. In the new tab, most of the prompts will automatically fill in for you.
-   - For owner, choose your personal account or an organization to host the repository.
-   - We recommend creating a public repository, as private repositories will [use Actions minutes](https://docs.github.com/en/billing/managing-billing-for-github-actions/about-billing-for-github-actions).
-   - Scroll down and click the **Create repository** button at the bottom of the form.
-3. After your new repository is created, wait about 20 seconds, then refresh the page. Follow the step-by-step instructions in the new repository's README.
+1. Open your `welcome.yml` file.
+2. Update the contents of the file to:
+   ```yaml
+   name: Post welcome comment
+   on:
+     pull_request:
+       types: [opened]
+   permissions:
+     pull-requests: write
+   jobs:
+     build:
+       name: Post welcome comment
+       runs-on: ubuntu-latest
+   ```
+3. Click **Start commit** in the top right of the workflow editor.
+4. Type your commit message and commit your changes directly to your branch.
+5. Wait about 20 seconds for actions to run, then refresh this page (the one you're following instructions from) and an action will automatically close this step and open the next one.
