I put a laminate floor down in my old house. It was easy but took time.
I would imagine a lot that is done for Laminate would also apply to real wood. Gaps around the edges, and a pad underneath so the wood can "Float".
Essential tools needed.
Bacon Sandwiches
Cans of lubricant LOTS - ie beer.
Boom box with good music
1 FBH
One very big box of Band Aids. You are going to smash your fingers AT LEAST once, probably more. I did and it hurt like a basket.
My only real piece of advice. Start in a room that has lots of stuff to cover the wood if you screw up. Like the Laundry room.
