Outline the technique. Compose an outline of each major step in performing a CR X-ray.
Detail the process. Use arrows to connect the major headings of your chart. This will visually illustrate a sequence to your learners and allow them to internalize the process of performing a CR X-ray.
Add visuals. Whenever possible, add in a picture to enhance the textual explanations. This will help anchor the learners' actual performance by allowing them to relate what they have done to a picture in your chart.
