Need some exercises for begginers

Hello! I am a 15m, i am 6'0  and i weigh 130 lb. I decided to start working out and gain some weight, but i don't know what exercises to do. I don't have access to a gym, i only have 2 8lb dumbbells. For now I'm doing pushups and hammer curls. I also plan on buying a pole for doing pull ups. Can someone recommend me some exercises?
