 #### Unsupported emojis fallback
 Certain sets don’t support all emojis (i.e. Messenger & Facebook don’t support `:shrug:`). By default the Emoji component will not render anything so that the emojis’ don’t take space in the picker when not available.

+#### Using with `dangerouslySetInnerHTML`
+The Emoji component being a [functional component](https://medium.com/missive-app/45-faster-react-functional-components-now-3509a668e69f), you can call it as you would call any function instead of using JSX. Make sure you pass `html: true` for it to return an HTML string.
+
+```js
+<span dangerouslySetInnerHTML={{
+  __html: Emoji({
+    html: true
+    set: 'apple'
+    emoji: '+1'
+    size: 24
+  })
+}}></span>
+```

 ## Custom emojis
 You can provide custom emojis which will show up in their own category.
