How to install hardwood flooring in a room?

To install hardwood flooring in a room, first, ensure the subfloor is clean and level. Acclimate the hardwood planks to the room's temperature and humidity. Start laying the planks from one corner, using a nail gun or adhesive to secure them. Leave space for expansion at the edges. Continue laying the planks row by row, staggering the joints for a natural look. Finally, trim the edges and add finishing touches like baseboards.
