I would like to setup and test the new features/UI of Umbraco 7 (Belle). Are there current installation/setup instructions along with system requirements anywhere online? I tried looking, could not find anything but am probably overlooking the obvious. I've download the latest codeset from GitHub but am also guessing I need Visual Studio 2012 or later. I demo/test package site would also be great if one is not included already. many thanks in advance!
