[RoboVM] Point me in the right direction?

I just recently learned about RoboVM. I’m really excited about how it can make Java applications into iOS apps. I really want to get started with it! So, where would I go to learn JUST RoboVM stuff. I can’t find many resources on RoboVM itself. I see a bunch of resources with RoboVM in combination with libGDX but I have no intentions to learn libGDX at this time. Can RoboVM even be used without libGDX? I don’t know. So, all I’m asking for is a little enlightenment on this marvelous sounding thing and where I should go to find a decent beginner tutorial. (I followed the one on the site. Didn’t help me at all.)
