It's like soccer, with the aspect of kicking the ball between uprights like rugby. When in possession of the ball you can take 4 steps and dribble it then after another four steps kick it, back to yourself, you cant dribble it twice. Also there is checking. You can advance the ball by running with it with the rules above, passing it, or kicking it like in soccer. Shooting the ball into the net either from the ground or by punting from your hands is worth 3 points while kicking it between the uprights is worth 1 point. Seems fun.
It is like a violent version of football and rugby mixed. try youtube and see if there are any clips.
I just thought it was like normal football but the teams were in gaelic
