The Wing Helper documentation is provided as a PDF file, referencing a set of demonstration videos uploaded to the YouTube. For the impatient, the videos are also linked here.
If you have any problems viewing Wing Helper educational tutorials, please try pressing the "Watch on YouTube.com" field in the lower right corner of the embedded video. You will probably want to watch the videos in "full screen" mode, and on the highest quality settings (see buttons in the lower right corner of the embedded video).
