The Relearn theme for Hugo loads the [**Font Awesome**](https://fontawesome.com) library, allowing you to easily display any icon or logo available in the Font Awesome free collection.
Browse through the available icons in the [Font Awesome Gallery](https://fontawesome.com/v5/search?m=free). Notice that the **free** filter is enabled, as only the free icons are available by default.
Once on the Font Awesome page for a specific icon, for example the page for the [heart](https://fontawesome.com/v5/icons/heart?s=solid), copy the HTML reference and paste into the Markdown content.
