One of the key objectives for MvvmCross v3 was to make 'Getting Started' easier.
We've made quite a lot of progress on this - especially through Nuget, through some initial documents and through community contributions like the Ninja coder for MvvmCross
However, there's still some setup barriers - especially while we're still ironing out the official integration with PCLs for Xamarin (although there is really great progress on that currently!)
Because of this, community posts which help people with setup knowledge are really very important - and one such setup guide is @PeterSvitz's guide at http://psvitz.com/xamarin-vs2012-pcl-mvvm-cross-v3-awesome1one1/
Completely awesome work - thanks @PeterSvitz - awesome :)
