With new users coming over to linux they may not know how to create this udev rule, there is no indication of how you create this udev rule, only the directory of where it should be made, this directory is in root and requires root privileges to be created, my suggestion is that you tell the user to do sudo nano /etc/udev/rules.d/70-wooting.rules and then explain how to use nano so that they can save and exit nano safely
to save and exit you do ctrl-x, y and enter in nano
