-_Welcome to "Communicate using Markdown"! :wave:_
+_Great job adding headers to the file :sparkles:_
 
-**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.
+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
-# This is an `<h1>` header, which is the largest
-
-## This is an `<h2>` header
-
-###### This is an `<h6>` header, which is the smallest
+![Image of Yaktocat](https://octodex.github.com/images/yaktocat.png)
 ```
 
 #### 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
+<img alt="Image of Yaktocat" src=https://octodex.github.com/images/yaktocat.png width=400>
