How can I get better at basketball?

Basket ball is my favorote sports. I love to play it and unfortuanatly I am very competative when it comes to basketball. But I only play against my same gender. Girls. Most guys who I want to play against won't play a girl. But anyways how can I get better at basketball? I want to be the best basketball player on the girls team at my school. I'm going to 8th grade too. Anyways, I want to be the best and there's not tryouts cause out school is very small. Whoever joins, joins. But I still want to be the best. Any advice on shooting and my footsteps and stuff. I'd appreciate it. :) thanks
