How do I change the feature item on the homepage?

It's possible to feature items on the homepage by adding a special tag, "featured" (slug: "featured"). The latest item published with this tag will be displayed on the homepage. Remove this tag or manipulate publish times to remove items.

If the item has an image, it should use a horizontal or square aspect ratio. Square is used on mobile. Up to two addition images are displayed and can be in any aspect ratio.
