 ## Running your code
 
-Your code needs to be put on a USB drive in a file called `main.py`. On
-insertion into the robot, this file will be executed. The file is
-directly executed off your USB drive, with your drive as the working
-directory.
-
-To stop your code running, you can just remove the USB drive. This will
-also stop the motors and any other peripherals connected to the kit.
-
-You can then reinsert the USB drive into the robot and it will run your
-`main.py` again (from the start). This allows you to make changes and
-test them quickly.
+Your code needs to be put in the `zone-0` or `zone-1` folder in a file called
+`forklift.py` or `crane.py` for the forklift and crane robots respectively.

 anything. No log file will be created.

-## Serial number
+## Logs
 
-All kit boards have a serial number, unique to that specific board,
-which can be read using the `serial` property:
-
-``` python
-r.power_board.serial
->>> 'SRO-AA2-7XS'
-r.servo_board.serial
->>> 'SRO-AA4-LG2'
-r.motor_board.serial
->>> 'SRO-AAO-RV2'
-```
+A log file is saved in the `output/` folder so you can see what your robot did,
+what it didn't do, and any errors it raised. Each log file is in a folder based on its
+date and time, so you can look back at your previous runs.
