Is there a Getting Started guide

Is there a Getting Started guide anywhere? I'm looking for the basic html/javascript needed to run these. It would be nice if the demos showed their code and how that fits into the basic framework?

e.g.

```
<html>
<head>
<script src='....../jsfeat-min.js'></script>
</head>
<body>
<img src='.....'>
<script>
....??
</script>
</body>
</html>
```
