+### Fetch
+
+Depending on your requirements, you may need a `fetch` polyfill for use
+in legacy browsers or NodeJS. There are a variety of polyfills and ways
+to install, so implementation is up to you. Here are two recommendations:
+
+```js
+// node
+require('isomorphic-fetch')
+```
+
+```js
+// browser
+import 'whatwg-fetch'
+```
