Bread baking

Hi,
so, I go to a point, where I use bricks to build a stove every time I want to burn something in my garden.
On the other note, I bake bread.
I want to combine these two. Does anyone experienced baking bread in outdoor environments?
Assuming I trust my rocks not to explode, what to look out for?
Any hints or tips how to build a little breadbaking stove?
