A step by step guide for implementing a QR code reader from scratch


I've been looking for a guide that goes over implementing a barcode or ideally QR code reader from scratch. All I get is 'import this computer vision library, then import this QR code library, then this is how you connect them'. I am not looking for this, I want to start from the basics.
