+
+## Step 1: Add headers
+
+_Welcome to "Communicate using Markdown"! :wave:_
+
+**What is _Markdown_?** Markdown is a [lightweight syntax](https://docs.github.com/github/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax) for communicating on GitHub. You can format text to add a heading, lists, **bold**, _italics_, tables, and many other stylings. You can use Markdown in most places around GitHub:
+
+- Comments on [issues](https://docs.github.com/issues/tracking-your-work-with-issues/about-issues), [pull requests](https://docs.github.com/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-pull-requests), and [discussions](https://docs.github.com/discussions/collaborating-with-your-community-using-discussions/about-discussions)
+- Files with the `.md` or `.markdown` extension
+- Sharing snippets of text in [Gists](https://docs.github.com/github/writing-on-github/editing-and-sharing-content-with-gists/creating-gists)
+
+**What is a _header_?** A header is a larger bit of text at the beginning of a section. There are six sizes.
+
+### Example
+
+```md
+# This is an `<h1>` header, which is the largest
+
+## This is an `<h2>` header
+
+###### This is an `<h6>` header, which is the smallest
+```
+
+#### How it looks
+
+# This is an `<h1>` header, which is the largest
+
+## This is an `<h2>` header
+
+###### This is an `<h6>` header, which is the smallest
+
+### :keyboard: Activity: Edit your file with headers
+
+1. Open a new browser tab, and work on the steps in your second tab while you read the instructions in this tab.
+1. Open the **pull requests** tab.
+1. Click **New pull request**, for the branches to compare, select `base: main` and `compare: start-markdown`.
+1. Click **Create pull request**.
+1. In this pull request, go to the **Files changed** tab. We made an empty file `index.md` for you.
+1. Select **Edit file** from the three dotted **...** menu in the upper right corner of the file view on `index.md`.
+1. On the **Edit file** tab, add a `#`, followed by a **space**, before any content you like to make it an H1 Header. You can add more headers, using one to six `#` characters followed by a **space**.
+1. Above your new content, click **Preview**.
+1. At the bottom of the page, type a short, meaningful commit message that describes the change you made to the file.
+1. Click **Commit changes**.
+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: Add an image
+
+_Great job adding headers to the file :sparkles:_
+
+Let's add an image. Include descriptive text in the square brackets. This text is read aloud for people using screen readers. It's also shown at times when your image doesn't display, such as when there's a poor connection. You can see the syntax for images below:
+
+### Example
+
+```md
+![Image of Yaktocat](https://octodex.github.com/images/yaktocat.png)
+```

+
+<img alt="Image of Yaktocat" src=https://octodex.github.com/images/yaktocat.png width=400>
+
+### :keyboard: Activity: Adding an image
+
+1. As you did before, edit the `index.md` file in this pull request.
+1. In the file, add the correct Markdown for your image of choice. Don't forget to include alt-text!
+1. Use the **Preview** tab to check your Markdown formatting.

+
+_Great job adding an image to the file :tada:_

+In addition to code blocks, some code blocks should be rendered differently depending on the language, such as JavaScript or command-line text.

+## Step 4: Make a task list
+
+_Great job adding a code example to the file :partying_face:_
+
+**What is a _task list_?** A task list creates checkboxes to check off. They're very useful for tracking issues and pull requests. If you include a task list in the body of an issue or pull request, you'll see a progress indicator in your issue list. The syntax for task lists is very specific. Be sure to include the spaces where required, or else they won't render.
+
+### Example
+
+```
+- [x] List syntax is required
+- [x] This item is complete
+- [ ] This item is not complete
+```
+
+#### How it looks
+
+- [x] List syntax is required
+- [x] This item is complete
+- [ ] This item is not complete
+
+### :keyboard: Activity: Add a task list
+
+GitHub Actions went ahead and made a branch for you. So you'll need to add to the file we've created in the branch, and we will check your work as you work through this course!
+
+1. Return to your pull request.
+1. Use Markdown to create a task list. Here is an example:
+
+   ```md
+   - [ ] Turn on GitHub Pages
+   - [ ] Outline my portfolio
+   - [ ] Introduce myself to the world
+   ```
+
+   Remember, a task list starts with the syntax `- [ ]` and then the task list item. The formatting is specific!
+
+1. Use the **Preview** tab to check your Markdown formatting.
+1. Commit the changes to the file.
+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.
