How do I install kitchen cabinets?
Measure the ceiling height every foot. It is likely there will be low and high points so you may want to split the difference between the counter and the ceiling (if you're not mounting to the ceiling.

Uppers go in first, primarily because they're hard to install once the lowers are in.

Install a ledgerboard to align and help install the uppers. Get long screws and pre-drill. I really prefer the star-head cabinet screws. 

As for the order of install, it depends on your room... do you have a large gap somewhere (like a hood for the range) or do you need filler strips somewhere?

Where will the fillers go? How will your lowers line up with the uppers? Will the gaps be wide enough for your appliances to fit?

The most important part of installing cabinets is planning and prepping.
