Hi!
The lesson isn’t asking you to add the list by copying and pasting, that was just an example.

Space indentation means adding spaces using the space bar to code to make nested code easier to read. It wants you to add two spaces in front of the h2, code comment and paragraph element.

This is indented code for reference.

<main>
  <h1>hello</h1>
  <section>
    <p>This is indented code</p>
  </section>
</main>
