+Place a turtle with an **inventory module** connected on the right like in the following image:
+
+![Centrifuge Turtle Setup](../images/centrifuge_turtle_setup.png)
+
+The leftmost interface should have a stack of cells, the middle one a stack of ingredients, e.g., redstone dust, and the rightmost should be empty.
+
+This program **does not** survive reboots/unloading! Keep it chunk-loaded and do not restart the server after starting the turtle.
+
+Make sure the turtle always has enough resources to keep going. If it has to wait too long, it will break eventually!! If this happens, manually take out all products from the centrifuges to fix it.
