My first app at Ionic

Hi all,
I am new to Ionic and just successfully able to setup the project. I was building a sample blank app and was adding some button to it. Unfortunatley, after following the steps mentioned in the link
http://ionicframework.com/docs/guide/starting.html
I am not able to see the changes in my UI.
Can some one help me.

Regards,
Vishnu
here is my html page.
application name app.
angular.module(‘app’, [‘ionic’])//added this item.

more code, np.: push on github

I don’t see any html in your post. Are you using ionic serve to preview the app?
