Took me a while but now I have a great bread.
I use 1 cup of starter (100% hydration) 1 cup of water and 3 cups of flour, 1 tablespoon of salt.
Mix it in the bread machine.
Take it out and put it in a loaf tin.
Rise all night. Doubles in volume!
Bake for 40 min at 200 C.
This dought is rather thin and sticky so it will nog hold it's shape without a tin.
Tastes great, not too sour which I don't like.
