 Please note that idb2 and 1700000000 are provided merely for illustration purposes and that the teams must allow for the values passed to be entered by the evaluators. Finally, no modifications to this execution format is allowed, and no additional fields will be used during evaluation.
 
-Teams should also implement their radios such that packets are drawn from port 5123, while packets are delivered to port 5125. An illustration of this can be seen in the Python code '''here'''.

+Teams are also required to label their image with the image name they intend to use for submission stored in file named '''/.orbit_image''' on the root of the filesystem. For example, if the team itends to submit image with image name '''orbit-bot.ndz''' the /.orbit_image shoudl contain '''orbit-bot'''.
