In a small container, combine the warm water and yeast, and stir. In a large bowl combine the flour and salt, and mix together with the yeast and water. Mix together until a dough forms, and knead until smooth and elastic. The dough should be firm with a slight spring. Place dough in an oiled bowl, and cover until dough rises and doubles in size, about 45 minutes to 1 hour.
Once the dough has risen, scrape dough from bowl onto a floured surface. Knead again, and shape into a disc. Cover dough and let rise again for about 45 minutes.
After the second rising, stretch dough out and shape it for your pizza. Dress the pizza as you wish, and bake for approximately 20 minutes.
