The library is the single JavaScript file card.js (or minified, card.min.js).
It can be loaded via a script tag in an HTML document for the browser
<script src='./relative/path/to/card.js'></script>
(check examples/browser) or as a CommonJS, Node.js.
For Node, put the card.js file into the same directory as the file that is requiring it and use
var card = require('./card.js');
or put it in a node_modules directory within the directory and use require('card.js'). See example in examples/nodejs.
The library is also available from the npm registry, so
$ npm install card.js
will install this module in a node_modules directory within the current directory.
