I just bought a beta fish.. now what?

I just bought a beta fish, a 1 gallon bowl, some pebbles, a plant for it, food, and water conditioner. It is still in its small container that i bought it with. How should i go about removing him from that small container to the new fish bowl i just bought? I know i have to be careful with the tap water. Please give me step by step instructions. I don't want him to die like my last beta. thank yoU!
