 Flaska will automatically close the file stream for you so you don't have to worry about that.
 
+### FileResponse
+
+Alternatively, if you want proper file support, I recommend using FileResponse object:
+
+```
+import { FileResponse } from '../flaska.mjs'
+
+flaska.get('/test.txt', function(ctx) {
+  return fs.stat('./test/test.txt').then(function(stat) {

+  })
+})
+```
+
+This performs a real file stream support, uses pipes and supports all the HTTP shenanigans when it comes to dealing with files, including sending proper etag header, supporting partial response and lots of other things. This is one of the few libraries that actually implements full HTTP partial and etag support in a proper way, almost all other have one or two quirks that don't follow the spec properly.

 ### String
 
 In other instances, Flaska will `.toString()` the body and send it in response with the specified type or default to `text/plain` if unspecified.
