Generously dust your Banneton with flour to prevent sticking (I like to use rice flour because it is very fine and gets into all the crevices easily, but plain, wholemeal, or semolina flour will do too)
Sprinkle your bench with flour, remove dough from the bag (turn the bag upside down and the dough should drop out if you oiled it correctly).
Stretch the dough out into a longish rectangle so that you can spread your fruit and nut over it (you don't need to "stretch and fold" the dough as you would do normally for a loaf, as the action of placing the fruit and nut onto it, and rolling it up acts like a "stretch and fold").
Drain your fruit and nut and spread it evenly over the dough
Start to roll the dough up from a narrow end, and roll until you get to the other end enclosing all the fruit and nut into the dough
Dust off any excess flour from the top and around the dough
Use your hands to gently shape the dough into a round being careful not to break the top of the dough skin (so that the fruit and nut is still enclosed on the inside of the dough)
Lift the dough up and place it upside down into the Banneton, with the joined section facing up
If necessary, gently press the joins together, but this is the section that will be placed first onto the baking tray so you won't see the join when it is baked)
