To ensure accuracy I cross reference what I am doing with others. I also run what I have done multiple times until I can understand what each button and click does.

To make complex tech topics simple I would begin by breaking down the idea behind what I am doing while simultaneously showing them the steps. At the end I would include image of all the steps in order for them to screenshot and always have available until they commit it to memory. I will do this through using simple terms and not complex technical terms that the average individual does not know and if I am required to use a such words I will explain each of them.
