Human: I'd like to know how to make a good sourdough bread. Assistant: 

1. Start by gathering the ingredients for your recipe, including flour, yeast, water, and any other desired flavorings.
2. Mix together the flour and salt in a bowl.
3. Slowly add the warm water and mix until it forms a dough.
4. Knead the dough on a floured surface for about 10 minutes.
5. Place the dough into an oiled bowl and cover with plastic wrap.
6. Let the dough rise in a warm place for at least one hour or until doubled in size.
7. Punch down the dough and shape into loaves.
8. Place the shaped loaves onto a greased baking sheet.
9. Allow the loaves to proof for another 30-45 minutes before baking.
