+# <qr-code>
+
+Web Component for generating QR Codes, using (a [fork](https://github.com/educastellano/qr.js) of) [qr.js](https://github.com/lifthrasiir/qr.js) lib.
+
+> Maintained by [Eduard Castellano](https://github.com/educastellano).
+
+## Demo
+
+> [Check it live](http://educastellano.github.io/qr-code/demo).
+
+## Usage
+
+* **NPM and Browserify** ([polyfill](https://github.com/WebComponents/webcomponentsjs) and the component):
+
+	Install:
+
+	```sh
+	npm install webcomponents.js
+	npm install webcomponent-qr-code
+	```
+
+	Import:
+
+	```js
+	require('webcomponents.js');
+	require('webcomponent-qr-code');
+	```
+
+* **Bower** ([polyfill](https://github.com/WebComponents/webcomponentsjs), [qr.js](https://github.com/educastellano/qr.js) and the component):
+
+	Install:
+
+	```sh
+	bower install webcomponentsjs
+	bower install webcomponent-qr-code
+	```
+
+	Import:
+
+	```html
+	<script src="bower_components/webcomponentsjs/webcomponents.min.js"></script>
+	<script src="bower_components/qrjs/qr.js"></script>
+	<script src="bower_components/webcomponent-qr-code/src/qr-code.js"></script>
+	```
+
+	> You can also import the component with [HTML Imports](http://w3c.github.io/webcomponents/spec/imports/), but you still need to import the polyfill and the qr.js lib separately:
+	>
+	> ```html
+	> <link rel="import" href="bower_components/webcomponent-qr-code/src/qr-code.html">
+	> ```
+
+* **Start using it!**
+
+	```html
+	<qr-code data="hello world!"></qr-code>
+	```
+
+
