All examples use the qrcode.Medium error Recovery Level and create a fixed

256x256px size QR Code. The last function creates a white on black instead of black
|

on white QR Code.

The maximum capacity of a QR Code varies according to the content encoded and

the error recovery level. The maximum capacity is 2,953 bytes, 4,296
|

alphanumeric characters, 7,089 numeric digits, or a combination of these.

## Borderless QR Codes
|
||||
|
||||
To aid QR Code reading software, QR codes have a built in whitespace border.
|
||||
|
||||
If you know what you're doing, and don't want a border, see https://gist.github.com/skip2/7e3d8a82f5317df9be437f8ec8ec0b7d for how to do it. It's still recommended you include a border manually.
