Get on the water and wait for wind?
Yeah! Try that.
Seriously, you can read all kinds of books on sailing, or do web searches, or watch YouTube videos, but once you have a general idea of how things work, the easiest way to learn on a boat like yours (or any recreational Hobie, really) is to get out in an open body of water without a lot of traffic, and see what the wind does. Don't pick a crazy windy day, but just go out, and have fun. Spending a few hours in light breezes can teach you a LOT that you'll put to memory if you experience it.
I have a Sailing For Dummies book, which is pretty good, but really, on boats like these, it's all about experience. Nobody cares if you know the proper terms for everything, you're not competing for social status at the yacht club, so just go out, see how things go, and if you're consistently having trouble with one thing or another, there will be lots of people on this forum to help you out. You'll probably find that a little bit of trial and error will teach you most of what you need to know.
