 Dynamically generated QR codes for modern browsers.  
 Uses [QR Code Generator][qrcode] (MIT).
 
+Choose between rendering the code as `canvas`, `img` or `svg`. The generated QR code will be in the least possible version requiered to encode the content (least number of blocks). Takes care of device pixel ratio to render crisp codes on all devices. Works in all modern browsers.
+
+<!-- See a #[a(href='latest/demo/', title='demo of the latest version') demo] to get a first impression. -->
+
+## Usage
+
+The syntax is simple. Use global method `kjua` to create a fresh `canvas`, `img` or `svg` element displaying the QR code and add it to your page. For example:
+```js
+var el = kjua({text: 'hello!'});
+document.querySelector('body').appendChild(el);
+```
+
+## jQuery
+
+A jQuery plugin is included, you can use it like
+```js
+$('#my_container').kjua({text: 'Hello'});
+```
+
+## Options
+
+The available options and their default values are:
+```js
+{
+    // render method: 'canvas', 'image' or 'svg'
+    render: 'image',
+
+    // render pixel-perfect lines
+    crisp: true,
+
+    // minimum version: 1..40
+    minVersion: 1,
+
+    // error correction level: 'L', 'M', 'Q' or 'H'
+    ecLevel: 'L',
+
+    // size in pixel
+    size: 200,
+
+    // pixel-ratio, null for devicePixelRatio
+    ratio: null,
+
+    // code color
+    fill: '#333',
+
+    // background color
+    back: '#fff',
+
+    // content
+    text: 'no text',
+
+    // roundend corners in pc: 0..100
+    rounded: 0,
+
+    // quiet zone in modules
+    quiet: 0,
+
+    // modes: 'plain', 'label' or 'image'
+    mode: 'plain',
+
+    // label/image size and pos in pc: 0..100
+    mSize: 30,
+    mPosX: 50,
+    mPosY: 50,
+
+    // label
+    label: 'no label',
+    fontname: 'sans',
+    fontcolor: '#333',
+
+    // image element
+    image: null
+}
+```
