### Bug description

I noticed that the shorcode example is missing in the reference page.
Perhaps the behavior of quarto has changed?

## Overview

Includes are a convenient way to re-use content across documents. Includes work for plain markdown content as well as for `.qmd` files with executable code cells (note however that the cells must all use the same engine -- i.e. knitr or jupyter, but not both).

To include a file, add the `{{< include >}}` shortcode at the location in your document where you want it included:

``` markdown
{{< include _content.qmd >}}
```
