+## Response chunking
+
+By default, the middleware writes the complete response at once but response
+chunking (aka HTTP Streaming) is available via a config switch:
+
+```js
+app.get('/*', fastbootMiddleware({
+  distPath: '/path/to/dist',
+  chunkedResponse: true
+}));
+```
+
+Enabling response chunking will result in the response being delivered in
+multiple chunks (one for the head, one for the body and one for each shoebox)
+which helps getting the HTML to clients faster.
