Cabinets are easy to install. READ the included instructions and you won’t have any issues assembling it.  One tip ….. do NOT tighten the two Allen key bolts in each corner (front and rear), 
until the doors are in and shelf and you have the cabinet on a level surface. The cabinet must be 100% square or the 
doors won’t line up.  Once the doors meet even and the gaps are even tighten all 16 Allen screws (8 front 8 in rear).  Some reviews critiqued this cabinet because doors wouldn’t line up.  Person is not knowledgeable about how to align doors or make cabinets!!!!!
