+### Custom subname
+
+Instead of using the `subname` prop you can use the same called slot. This is handy if you need to add accessible information.
+Like in the following example where the goal is to show a star icon to mark the file a favorite.
+Simplying adding `★` would not work as screen readers might not or wrongly announce the icon meaning this information is lost.
+
+A working alternative would be using an icon together with an `aria-label`:
+
+```vue
+	<template>
+		<NcAppSidebar name="cat-picture.jpg">
+			<template #subname>
+				<NcIconSvgWrapper inline :path="mdiStar" name="Favorite" />
+				123 KiB, a month ago
+			</template>
+		</NcAppSidebar>
