lay down the underlayment, or sound proofing foam first. tape it with duct tape or similar to hold the strips in place, and trim at the walls to fit.
put the 1/4" spacers along one wall, or use a spare laminate board, and start laying the first row.
I made my own tap blocks from maple, but you can buy the plastic ones, too.
tap each board in till it locks into the previous one.
leave 1/4" space all around the edges at the walls, which will allow for expansion/contraction, and be hidden by the base board molding.
cut the ends with a table or chop saw, or barring those, a mitre box and hack saw.
you can usually do a typical room in a day.
