     Paste image files with command line. You can give <u>-F</u> more times to paste
     more images.
 
+    You can also add a <u>?qr</u> parameter to receive a QR code together with your
+    image URLs like this:
+
+    curl -F 'name=@/path/to/image' '{{ url }}?qr'

 EXAMPLES
     <span style="color:#ffc000" >$</span> curl -F 'name=@screenshot.png' {{ url }}
