 Then open `index.html` in a browser of choice. You're now ready to use your `level` database, backed by IndexedDB!
 
+In order to reduce bundle size, the [`buffer`](https://github.com/feross/buffer) polyfill is excluded. To store binary data, either change browserify configuration, or use Uint8Array instead of Buffer. For example:
+
+```js
+import { Level } from 'level'
+
+const db = new Level('browserify-starter', {
+  keyEncoding: 'view'
+})
+
+await db.put(new Uint8Array([1, 2]), 'example')
+const example = await db.get(new Uint8Array([1, 2]))
+```
