Welcome to the forum! I'd suggest watching as many videos and reading as many books on the shooting sports as you can. For starters I would get something like a bolt action .22. Maybe like a Ruger American Rimfire in .22lr, since ammunition is by far the cheapest, and the light recoil. Then you're going to need to find a range, I'm sure there are a lot up your way. Make sure you review the rules of firearms safety thoroughly, there is a copy of these rules above in the blue box next to "Forum Rules". Safety is the number one thing. After you have learned them you can put them to practice when you go to the range, like not pointing the muzzle at anything you don't want to destroy, and keeping your finger off the trigger until you're ready to fire. I could go on typing forever about things but it would get a bit repetitive and would take forever. Make sure you also read and watch about proper sight alignment, trigger press, and breathing. I would also recommend shoting from a stable bench rest with iron sights until you develop your skills, then you could practice offhand shooting, etc.
Good Luck!
