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

If you don't have a tortilla warmer, wrapping your tortillas in foil and towels will keep them warm for about 15 minutes. For tortillas that weren't heated in a stack, stack them up to eight high. For stacks that aren't covered in foil, wrap each stack of tortillas in foil. Wrap each pack in a towel. Tortilla warmers are round containers with removable lids, and they keep tortillas warm longer than the foil and towel method. They are often made of plastic, ceramic, or terra cotta, and some are designed for the oven, the microwave, or both. Most tortilla warmers also double as warming containers that you can reheat tortillas in directly. To heat tortillas in the tortilla warmers, most require a damp paper towel in the bottom of the container, followed by about eight tortillas. Follow the manufacturer’s instructions about heating. With a cloth tortilla warmer, place the tortillas inside the cloth shell and heat them in the microwave. The insulating and moisture wicking cloth and plastic shell then keeps the tortillas warm and soft—but not soggy—for over an hour.

Summary:
Wrap them in foil and a towel. Place them in a tortilla warmer. Use a cloth tortilla warmer. Finished.
