+### FormattedHTMLMessage support (react-intl pre-v4)
+
+Out of the box, this example does not support the use of the `FormattedHTMLMessage` component on the server due to `DOMParser` not being present in a Node environment.
+This functionality is deprecated and has been removed as of react-intl 4.0
+If you still want to enable this feature, you should install a `DOMParser` implementation (e.g. `xmldom` or `jsdom`) and enable the polyfill in `server.js`:
+
+```js
+// Polyfill Node with `DOMParser` required by formatjs.
+// See: https://github.com/zeit/next.js/issues/10533
+const { DOMParser } = require('xmldom')
+global.DOMParser = DOMParser
+```
