Find a reputable shop that can fit the bow to you. I never realized how intricate a process this was until I bought a compound bow. Draw length needs to be correct, peep sights need adjusted for height so you can see through it at full draw etc. You may need arrows sized as well. Would also be a good idea to have the draw weight measured so you know what kind of arrows you can use.
It shouldn't be overly expensive to have it tuned up once and after that you can easily maintain it yourself. It will shorten the learning curve a lot. Welcome to the addiction
