1. Measure and trim the door if needed.
2. Mark hinge locations on the door and create recesses with a chisel.
3. Attach hinges to the door frame.
4. Install the doorknob/handle set and latch/lock mechanism.
5. Position the door in the opening and check alignment with a level.
6. Screw the hinges onto the door frame.
7. Test the door's movement and ensure proper latching/locking.

2. Score the outline of the hinge with a utility knife or chisel.
3. Use a chisel and hammer to gradually remove wood within the marked area.
4. Clean up the recess and ensure a smooth surface.
