 ### 3. How do I handle responses with types like `'stream'`, `'document'`, `'arraybuffer'`, or `'blob'`?
 
-To handle such responses, use the `responseType: 'stream'` option in your request:
+> Currently in `xior`, when `responseType` is set to `'stream', 'document', 'arraybuffer', 'blob', or 'original'`, Xior will return the original fetch response.
+
+```ts
+fetch('https://exmaple.com/some/api').then((response) => {
+  console.log(response);
+});
+
+// same with
+xior.get('https://exmaple.com/some/api', { responseType: 'blob' }).then((res) => {
+  console.log(res.response); // res.data will be undefined
+});
+```
+
+And to handle a stream response, use the `responseType: 'stream'` option in your request, then do something with the `response` as `fetch` does:
