Start by gathering all your ingredients. You'll need the following things:
1 c. sourdough starter*
6 c. bread flour**
3 c. water
2 t. salt
1/4 t. yeast
*information on sourdough starter is in the next step
** Bread flour works best, but all-purpose flour will also work out just fine. If you want a whole wheat loaf, you can substitute whole wheat flour in a roughly 1 to 1 proportion. I personally find that a loaf made of 100% whole wheat flour, especially flour I grind myself, a little too heavy for my family. Using 50% home-ground whole wheat flour produces a nice loaf. Some of the rise times might need to be adusted if your kitchen is cool.
