 ## Updating to the latest Github code
 It might be that the current portable release is behind the active development tree and your issue was already solved in the meantime.  
 To update to the latest Github code you can download and extract the current portable release [VXX.X_Portable.zip](https://github.com/sanni/cartreader/releases) and [the latest development tree](https://github.com/sanni/cartreader/archive/refs/heads/master.zip) and then copy all the *.ino files from cartreader-master.zip\cartreader-master\Cart_Reader\ to VXX.X_Portable\Arduino IDE Portable\portable\sketchbook\Cart_Reader\. Then follow the [update guide](https://github.com/sanni/cartreader/wiki/How-to-flash-the-Arduino#to-upload-the-firmware-to-the-cart-reader-please-follow-these-steps).
