i want to know how to start with ionic
Probably the best way is to start here:
You can create your first Ionic project as one of three starter templates - blank, tabs, sidemenu. If you choose tabs or sidemenu your project will include small sample application that does pretty much nothing but contains basic interface. You can easily modify it and add more UI components to this interface.
Look here http://ionicframework.com/docs/components/ to see what UI component are included in Ionic. There’s always an example so you can just copy & paste it to your app and start modifying it.
Hope it helps.
