It's not too complicated, just heavy. The pin hood & alley sections should be attached to the cabinet with bolt screws. Just make sure to unplug all the jones plugs that run from the hood/lane sections into the inside of the cabinet first before you start unbolting anything. You don't want to break those.
Basic tools (pliers, socket set, screw drivers), a hand truck, and a strong back if your moving up stairs. I've been there, Good luck.
