According to the website, TeacherTap, "Writing quality instructions require a knowledge of the hardware or software, as well as skills in writing." Check out their article on Writing How To's (PDF document)  file to learn more about writing step-by-step instructions. 

The website further states that, "...regardless of whether you're working with children or adults, there are many things to consider when writing step-by-step instructions: What's the reading level of the user? What is their experience with computers? What specifically do you want your learner to do? How can you provide the most independent environment for your learner?

As we begin to explore creating our own technical documentation, we need to keep all of this in mind.
