What is QR Code Design?

Question

Design

Hello everyone, where can I read about the design of a QR code? Which elements can be modified in general, and which not, in order for the code to be scanned correctly?
For example, can I split the QR code in half, rotate it, change the shape of the pixels, insert a logo in the middle?
