 # The complete product example :bulb:
 
-This project demonstrate how to deal with a real life project using Luos_engine. This project deal with custom project type, custom message commands, and demonstrate how to adapt your gate and pyluos to properly handle it.
+This example demonstrates how to deal with a real life project using Luos_engine. This code folder deals with custom types, custom messages commands, and demonstrate how to adapt your gate and pyluos to properly handle it.
 
-This project is a laser Galvo controller that can be use in an engraving machine, a small surface laser cutter or a laser show device.
-This have been tested with the great [interface board made by the opengalvo OPAL project](https://github.com/leswright1977/OPAL_PCB)

+This has been tested with the great [interface board made by the opengalvo OPAL project](https://github.com/leswright1977/OPAL_PCB) on STM32-L476RG and a simple cat laser pointer toy.

 This product is composed of multiple nodes:
 
 - A gate node called `custom_gate` running on your computer
-- A laser Galvo node called `laser_galvo` running on a microcontroller (tested on nucleo_l476rg but should work on most of the STM32 family)
+- A laser Galvo node called `laser_galvo` running on a microcontroller (tested on STM32-L476RG, but it should work on most microcontrollers within the STM32 family).
+
+In this folder, you can also find a Python notebook `laser_galvo_control.ipynb` to control the laser Galvo.
