Great bike! Besides tutorial videos on you tube, many mtb clubs do offer skills classes. Also, you could try to meet experienced riders and ask for help.

Otherwise, stay within yourself and take your time working up to the challenges on the trail. It's better to walk a section than to get injured. I have a lot to learn myself but I try to avoid crashing whenever I go riding. I've crashed off-road motorcycles, mountain bikes, and road bikes. Crashing sucks.
