I'm with moodtysabre, try it out! I tend to leave the genoa set until the kite is flying, that stops the kite going inside the forestay.
Un-snuff it with apparent wind about 20-30 degrees off the stern, any lower it will be too blanketed probably. How high you can head up depends on boat and windspeed, but in general, try gently heading up until the boat feels well powered. If it feels overpowered, bear away. The helm is the main power control! As a relative beginner, don't set the kite unless you have plenty of space to bear away into! Use your speedo/log to find the best points of sailing.
Don't worry about gybing it to start with, just snuff it and move the sheet to the other side.
In light weather, the kite will set with the wind well forward of the beam, but it may not be helping much.
Be aware that these sails can find a lot of power in relatively light winds, so keep turns on the winch and wear gloves. But these sails can really make downwind enjoyable in light airs.
