Documentation_

I know we watch a few videos on “how to” and I found a video on youtube in which the purpose is to teach the audience, how to remove scratches from any DVD. Documentation in form of a video is helpful if and how the creator demonstrates the purpose, evidence, steps etc. In this video the creator explains the process and at the same does the experiment for better understanding.
