Tips on how to assemble when you get to the doors, have one person holding it still as high up as it can go while the other person nails it in. Afterwards, adjust the doors by using the screwdriver to screw the bottom nail tighter and the top nail looser using the nail circled in red (see photo). This is a game changer! The doors actually fit perfectly and do not bump into each other if you do this step. 
Overall really nice appearance, lots of storage space, and the doors close softly and slowly which is nice. In love with this piece!
