          element: document.getElementById('qr'),

          value: 'https://github.com/neocotic/qrious'

Open up `demo.html` in your browser to play around a bit.

Simply create an instance of `QRious` and you've done most of the work. You can control many aspects of the QR code

using the following fields on your instance:

| --------------- | ------- | -------------------------------------------------- | ------------- | --------- |

qr.value = 'https://github.com/neocotic/qrious';

The QR code will automatically update when you change one of these fields, so be wary when you plan on changing lots of

fields at the same time. You probably want to make a single call to `set(options)` instead as it will only update the QR

  value: 'https://github.com/neocotic/qrious'

These can also be passed as options to the constructor itself:

You can also pass in an `element` option to the constructor which can be used to generate the QR code using an existing

DOM element, which is the only time that you can specify read only options. `element` must either be a `<canvas>`

element or an `<img>` element which can then be accessed via the `canvas` or `image` fields on the instance

respectively. An element will be created for whichever one isn't provided or for both if no `element` is specified,

which means that they can be appended to the document at a later time.

  element: document.querySelector('canvas'),
