How to use plugins in Dojo

Hy Friends, sorry I’m newbie in Dojo
I just try to create simple dojo html like Hello Dojo
but it doesn’t show all, it just show Hello in my browser

Tutorial: Hello Dojo!

Hello

<script>
   
    require([
	'dojo/dom',
	'dojo/domReady!'
		], function (dom) {
		var greeting = dom.byId('greeting');
	greeting.innerHTML += ' from Dojo!';

});

and the result just Hello not Hello from Dojo
is there something wrong or I missed something so the code doesn’t work (maybe wrong directory)?

Thank You
Steve
