Super simple. Did this in a few hours taking my sweet time. I used the Allure brand from Home Depot - and because a few boxes had been opened, I managed to talk the manager into 50% off :)
Just put it down, line up the next plank, etc etc. It's really hard to mess it up.
Then, what I did is took a rolling pin and used my body weight to go over the floor and press it all down. Worked perfectly, and saved money by not renting a roller from home depot.
Been installed for about 6 months now, no issues. The only thing I noticed is if you drop something sharp, it will make a little ding / scratch - but that'll happen on most flooring anyways!
