Umbraco v5, MVC
If you just want to know what umbraco is, I would suggest that you install 4.7 and learn and quit; it is stable and feature rich, although it uses webforms technology. There is a book about the Amazon that gives you a decent overview and a lot of help can be found on the forums at http://our.umbraco.org/forum
Once you understand what umbraco is then grab v5 for vortex. It's not quite as feature rich, but understanding all the features that were in 4.7 will give you a better idea of what v5 will do when all the features and additions are added. v5 is completely new, just released and is a completely new architecture based on MVC.
For v5, install umbraco and set it for dev dataset. its a very simple app showing a few things about umbraco ... but there is definitely no "fictitious umbraco v5 book setup guide". It takes you to earn your hands and understand ... or better yet, take one of the certification courses they offer and you will get speed even faster.
