after you lvl up and get your new ship how do get to use it where does it go any halp please

You go to ship requisitions and pick your ship. Then go back downstairs and look around till you see the command for select ship. Hit F or click it and then select your new ship as primary. Then go to the ship customization guy and make it the way you want it. You can also rename it once for free by going to your info tab.
