After your delayed fermentation in the fridge is complete, and you are ready to shape and bake.
Remove the dough from the fridge (it will have risen quite a bit) and let it rest at room temperature for at least 30 minutes.
On a very lightly floured, clean counter, gently remove the dough onto the counter and separate into two halves. The dough should not be very sticky, and quite soft and almost jiggly.
Working with one half at a time, gently flatten and stretch out the dough into a rough square (careful not to squish out all the air bubbles!). Fold it over onto itself envelope style. Flip it over and gently start to pull and the ball toward you along the counter, rotate and pull a few times to shape it into a round. Make sure not to punch down or deflate it as you go. Be gentle here. (Theres a few good shaping videos on youtube if you need some guidance on this). I find it tends to shape better when my counter is not very floured at all so that the dough has the counter to grab onto as you shape it.
When the dough is nice and round and smooth all over. Place the kitchen towel over it and set aside.
Repeat with the other half of the dough.
Cover both rounds with a kitchen towel and allow them to rest for 30 minutes.
Meanwhile, prepare your 'banneton' for the dough. If you don't own a proper banneton, you can make your own - line a round bowl roughly the size of the loaf you want to make (same size or a bit smaller than your baking dish) with a thin kitchen towel. Sprinkle the kitchen towel or banneton with some rice flour and semolina to coat the bottom and sides to prevent the dough from sticking as it rises. (You want to use a different flour than the actual bread so that it doesn't absorb into the dough!)
Back to your dough - remove the kitchen towel and give them one more gentle shaping.
Using a bench scraper, or your hands, gently lift the dough off the counter and place into the banneton upside down (so you should see the seam side up - smooth part down).
Sprinkle with more rice flour and loosely cover with a kitchen towel. Let this rest and rise at room temp for a final proof. About 2-3 hours.
The dough should rise up about 25%. Don't let it get any bigger than this or you will end up with over proofed dough which will deflate when you bake it (it will still taste fine though - so don't worry if you do overproof).
