QuickerSite is available on GitHub as from 2020.
You may want to star, fork, follow, download and/or contribute to the project over there. Thank you!
I found a nice (and free) Google service to generate QR-codes.
The service is extremely easy to use. All it takes, is use an image (<img>) tag and pass the url of your website as a parameter:
<img src="http://chart.googleapis.com/chart?cht=qr&chs=150x150&choe=UTF-8&chld=H&chl=http://www.quickersite.com" />
You can change its size by playing with the chs-parameter!
Check it out with your smartphone!
