-## Welcome
+## Step 1: Add a test workflow
 
-[Continuous integration](https://en.wikipedia.org/wiki/Continuous_integration) can help you stick to your team’s quality standards by running tests and reporting the results on GitHub. CI tools run builds and tests, triggered by commits. The results post back to GitHub in the pull request. The goal is fewer issues in `main` and faster feedback as you work.
+_Welcome to "GitHub Actions: Continuous Integration"! :wave:_
 
-- **Who is this for**: Developers, DevOps Engineers, new GitHub users, students, teams.
-- **What you'll learn**: What continuous integration is, how to use GitHub Actions for CI, how to create a workflow that runs tests and produces test reports.
-- **What you'll build**: We'll use [remark-lint](https://github.com/remarkjs/remark-lint) to check the consistency of Markdown files.
-- **Prerequisites**: We assume you've completed [Hello GitHub Actions](https://github.com/skills/hello-github-actions) first.
-- **How long**: This course takes less than two hours to complete.

+![An illustration with a left half and a right half. On the left: illustration of how GitHub Actions terms are encapsulated. At the highest level: workflows and event triggers. Inside workflows: jobs and definition of the build environment. Inside jobs: steps. Inside steps: a call to an action. On the right: the evaluated sequence: workflow, job, step, action.](https://user-images.githubusercontent.com/6351798/88589835-f5ce0900-d016-11ea-8c8a-0e7d7907c713.png)
 
-1. Add a test workflow
-2. Fix the test
-3. Upload a test report
-4. Add branch protections
-5. Merge your pull request
+- **Workflow**: A workflow is a unit of automation from its start to finish, including the definition of what triggers the automation, what environment or other aspects should be taken into account during the automation, and what should happen as a result of the trigger.
+- **Job**: A job is a section of the workflow, and is made up of one or more steps. In this section of our workflow, the template defines the steps that make up the `build` job.
+- **Step**: A step represents one _effect_ of the automation. A step could be defined as a GitHub Action, or another unit, like printing something to the console.
+- **Action**: An action is a piece of automation written in a way that is compatible with workflows. Actions can be written by GitHub, by the open source community, or you can write them yourself!
 
-### How to start this course
+To learn more, check out [Workflow syntax for GitHub Actions](https://docs.github.com/actions/using-workflows/workflow-syntax-for-github-actions) in the GitHub Docs.
 
-<!-- For start course, run in JavaScript:
-'https://github.com/new?' + new URLSearchParams({
-  template_owner: 'skills',
-  template_name: 'test-with-actions',
-  owner: '@me',
-  name: 'skills-test-with-actions',
-  description: 'My clone repository',
-  visibility: 'public',
-}).toString()
--->
+First, let's add a workflow to lint (clean, like a lint roller) our Markdown files in this repository.

+### :keyboard: Activity: Add a test workflow
 
-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/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 a new browser tab, and work through the following steps in that tab while you read the instructions in this tab.
+1. Go to the **Actions tab**.
+1. Click **New workflow**.
+1. Search for "Simple workflow" and click **Configure**.
+1. Name your workflow `ci.yml`.
+1. Update the workflow by deleting the last two steps.
+1. Add the following step at the end of your workflow:
+   ```yml
+   - name: Run markdown lint
+     run: |
+       npm install remark-cli remark-preset-lint-consistent
+       npx remark . --use remark-preset-lint-consistent --frail
+   ```
+   > Even after the code is indented properly in `ci.yml`, you will see a build error in GitHub Actions. We'll fix this in the next step.
+1. Click **Commit changes...**, and choose to make a new branch named `ci`.
+1. Click **Propose changes**.
+1. Click **Create pull request**.
+1. Wait about 20 seconds and then refresh this page (the one you're following instructions from). [GitHub Actions](https://docs.github.com/actions) will automatically update to the next step.
