 Change NeoPixel color
 ---------------------
 
-If you want your code to do more than just serve web pages,
-use the start/poll methods as shown in this example.
+In your handler function you can access the query/GET parameters using ``request.query_params``.
+This allows you to pass data to the handler function and use it in your code.
+Alternatively you can use URL parameters, which are described later in this document.
 
 For example by going to ``/change-neopixel-color?r=255&g=0&b=0`` or ``/change-neopixel-color/255/0/0``
 you can change the color of the NeoPixel to red.
 Tested on ESP32-S2 Feather.
