 Also, he makes the [pre-compiled Windows client](https://www.proxmarkbuilds.org/) so you can download it and run your PM3 client on Windows instantly.  
 I included his compiled client in my releases so you can use the GUI on the fly, and you can also use the GUI with your prefered client.  
 Great thanks to him.
