You work in a field related to your major or a field of your interest and your supervisor asks you to create instructions for something you do daily at work. The audience of the instructions is entry-level interns majoring in that field but who have no experience with the job or any specialized tools it requires. Your instructions should describe a simple, easily-conducted process related to your major. Avoid illegal, unethical, and potentially dangerous topics, but try to find something interesting.
Your audience is a non-specialist audience. Assume that your user is completely ignorant of the task at hand. I want to see you think through everything involved, even with a simple topic, and be very clear.
