How to install hardwood floors in a room?

To install hardwood floors in a room, first prepare the subfloor by ensuring it is clean, level, and dry. Acclimate the hardwood planks to the room's temperature and humidity. Begin by laying a moisture barrier, then start laying the hardwood planks from one corner of the room, working towards the opposite wall. Use a nail gun or adhesive to secure the planks in place. Finish by adding trim and transitions for a polished look.
