I have a problem. I don't know where to put jQuery EasyUI in CakePHP? Which folder?

Do I use it like a helper? 

Do I have to put something like:

```
var  $helpers = array('jQuery');

```

Do I have to put some in view?

Thank you so much for your help always. :)

Edit:

And if you can give me some online tutorials with jQuery EasyUI with CakePHP 2.x. (I already Google it.) :D
