Well welcome and enjoy the forum and the sport of archery and when the time comes, bowhunting. The advice given is correct. Have the bow set up for you perferrably by an archery shop. Most of those people know what they are doing.
Also have them show you how to shoot. There is a lot more to it than pulling back and letting an arrow fly. There are little things that make a big difference such as your grip. These things come natural for those of us who have been shooting a long time (I have been shooting a bow for over 50 years and I still love it.). Good luck, and don't be afraid to ask any questions.
