In one sentence, describe what the following article is about:

The pattern you’re laying your flooring in will affect how much you need. Measure the square footage of your floor (1 square meter is about 10.5 square feet). Then add 5-7% more square footage to account for waste if you’re laying your boards straight. Add 15% waste if you’re laying the floors in a herringbone pattern. There are plenty of places you can order your flooring from, such as home improvement stores, flooring wholesalers, and construction contractors can all order flooring for you. It's probably best to look at the flooring online or in-store before you decide on which flooring you want for sure. If you’ve chosen free-floating, or laminate, flooring, test fit 2 pieces by clicking them together. If it comes apart easily or doesn’t join securely, avoid it and purchase a different variety to avoid problems down the line. Open your boxes of engineered hardwood in the room where you’ll be installing it. Make sure the pieces are flat, not leaning against something, which could warm them. Allow the flooring to sit for 3 to 4 days in that room so it can acclimate to the temperature and moisture and expand or contract as necessary. If you’ve recently installed new drywall or plaster, wait at least a week before opening your boxes of hardwood. The moisture present in most basements and garages is bad for engineered hardwoods. It can warp the wood and permanently damage it.

Summary:
Measure the square footage of your floor. Order your floors. Let the flooring acclimate for 3 to 4 days. Avoid storing the hardwood in the basement or garage.
