Adding Existing Cordova Project into Visual Studio

I´ve just started to use CTP3.1 for visual studio 2013.

I´m creating a angularjs-ionic application, and I´d like to be able to download and run some ionic examples which are available on the web, such as https://github.com/bgoetzmann/ionic-persistence (just to quote one).

I´ve noticed that, usually, the examples applications found under github have a different structure other that Visual Studio´s (probably, they have the "dist" structure of VS). Usually, they relly on grunt or gulp + bower to perform some build tasks too.

What would be the recommended way of picking up such projects and importing them into VS?

Is there any efficient way of doing so, other than trying to copy and paste them into a new Cordova Project?

Thanks
