If you want to learn the proper way, first google circular breathing and master that. After that just practice the different fingering notes (which shouldn't be hard to figure out if you have something to compare tone too) and play away. If you can figure out circular breathing but are having problem with the fingering then PM me and I'll help you with it. I've played wind instruments for about 20 years now and they are all fairly similar.
Sadly the people I've seen play don't play properly using circular breathing method so the more who do it, the better.
