+### Language Aliases
+
+Language aliases are useful when we have to resolve deprecated locale (e.g `zh-CN` is technically `zh-Hans-CN`). Without aliases we would resolve `zh-CN` to `zh` which is less accurate. In order to include lang aliases, you can do:
+
+```js
+import '@formatjs/intl-relativetimeformat/polyfill';
