Could you explain me step by step how to make bread at home?
Sure, there are large variety of bread made in different part of the world, but the basic simple bread remains almost same, one of the recipie is given below: 

Ingredients 
1 package (1/4 ounce) active dry yeast
3 tablespoons plus 1/2 teaspoon sugar
2-1/4 cups warm water (110° to 115°)
1 tablespoon salt
6-1/4 to 6-3/4 cups bread flour
2 tablespoons canola oil


Steps: 

1. In a large bowl, dissolve yeast and 1/2 teaspoon sugar in warm water; let stand until bubbles form on surface. Whisk together remaining 3 tablespoons sugar, salt and 3 cups flour. Stir oil into yeast mixture; pour into flour mixture and beat until smooth. Stir in enough remaining flour, 1/2 cup at a time, to form a soft dough.
2. Turn onto a floured surface; knead until smooth and elastic, 8-10 minutes. Place in a greased bowl, turning once to grease the top. Cover and let rise in a warm place until doubled, 1-1/2 to 2 hours.
3. Punch dough down. Turn onto a lightly floured surface; divide dough in half. Shape each into a loaf. Place in 2 greased 9x5-in. loaf pans. Cover and let rise until doubled, 1 to 1-1/2 hours.
4. Bake at 375° until loaf is golden brown and sounds hollow when tapped or has reached an internal temperature of 200°, 30-35 minutes. Remove from pans to wire racks to cool.

Hope that's tasty and enjoy the bread.
