YouTube videos are extremely useful to easily share an animated content such as a step-by-step guide or an how-to movie. It is worth considering adding a YouTube video in an HTML based documentation, such as a CHM help file, to showcase a procedure and make it more easily and rapidly understandable by the end-user. As an added advantage, the video file won't be embedded in the final documentation but streamed directly from YouTube, thus lowering the final documentation's size.
