 ## Introduction
 This project provides a simple QR code generator for the 650x family. 
 
+Note: 
+The code is mostly specifically taylored for the Atari 2600 and a version 2 QR code. Other platforms or QR code versions have not been tested. But it should be adaptable without too major problems.

 ## Features
 - easy to use DASM macros
 - assembler switches to taylor generator to your needs
