One of the most requested features of Nitro is more documentation. Every user of Nitro realizes the possibilities of its sophisticated design. But it is difficult to grasp all the features and how exactly to use them. Better docs are still on our todo list, but today we released the first two Nitro/Og screencasts. You can find them here:

Be warned though: these videos are aimed to Nitro beginners and only demonstrate some simple features of Nitro. But I am sure that you will like them anyway. I really hope that these videos will make more Ruby developers take the time to experiment with Nitro and Og.
One of the next screencasts will demonstrate some truly innovative Og features that are simply not available in AR. Stay tuned for this ;-)
