I had a video and some text documents giving me examples of the proficiency I needed to develop in a subject. I needed to learn the content and demonstrate it. More than once the text documents did not provide sufficient detail or screenshots for understanding. Instead of clicking around the software at random, I turned to the video to see how the presenter handled the concept. A common application of this process is bypassing instructions included with a product and instead watching a video on YouTube or another site. Entire homes have been built or remodeled from knowledge gained on YouTube.
