Measure the wall to mark the size hole needing to be cut for the safe. Cut along the marks to create a hole in the wall. Slide your safe into the hole. Fix the safe to the studs by drilling through the holes in the sides of the safe. Insert the shelves."
You will want to fix your safe between studs to allow it to be recessed inside your wall and thus less noticeable. Use a stud finder to locate the studs behind the wall by running the stud finder across your wall. The tool will have an indicator to show when it has found a stud.  Stud finders can be purchased from your local hardware store. If you don’t have a stud finder you can knock on the wall and listen for a hollow or solid sound. If the sound is hollow then the location is probably between studs; if it sounds solid then there is likely a stud in this location. Knock a nail into the wall. As you hammer you will be able to feel if you hit a stud by the way the nail goes into the wall. These holes will be covered once you have installed your wall safe. Use a pencil to mark the locations of the studs on the wall. This will help orient your lines when you cut out the section of the wall. After you’ve found a good safe and a place to install it between studs, you are ready to cut into your wall. Cut out a small square of space big enough for your hand to fit through. If you find wires you need to be extra careful to go around them or reroute them. If you find plumbing in the way you may need to find a new location. If the wall is clear, you are ready to cut out a space for your safe. If something is in the way and you are not confident in your ability to safely move or go around it, the best option is to find a new section of wall. Mark the four corners of your square hole using a pencil. Use a level to make level lines between the four corners. It is essential that the top and bottom are parallel with the ground while the sides are parallel with your studs.  The hole should be close enough to a stud so that you can attach it to your safe later. Make sure to measure and level correctly so that you don’t end up with an uneven or wrongly sized hole. Use your drywall saw to cut along the marked lines. Start with the bottom edge of the opening and then cut the sides. You should cut the top line last to make sure the piece does not fall out beforehand, creating an uneven line. Put your safe into the hole, remembering to keep it help up with your hand. The door is the heaviest part of the safe due to the locking mechanism so be careful to hold up the corner so that it doesn’t fall out on you. Drill holes into the sides that match with the holes on the interior of your safe. Drill in each screw and then tighten them firmly. This is an important step that prevents burglars from simply cutting your safe out of the wall and walking away with the whole thing. Place the shelves inside the safe in their desired locations, making sure you line them up correctly. Some shelves will have cutouts to make space for the door locking mechanism and door hinges; make sure these cutouts are in the correct locations.
