Bookmarks are configured in the `bookmarks.yaml` file. They function much the same as [Services](services.md), in how groups and lists work. They're just much simpler, smaller, and contain no extra features other than being a link out.
The design of homepage expects `abbr` to be 2 letters, but is not otherwise forced.
You can also use an icon for bookmarks similar to the [options for service icons](services.md#icons). If both icon and abbreviation are supplied, the icon takes precedence.
By default, the description will use the hostname of the link, but you can override it with a custom description.
