Hello,

while looking at the videos and the video-repository, I noticed that we
don't have any license attached to neither the videos nor the sources.

I think we should really add one. For the code I would suggest GPL v3+,
for the voices (currently Paul) and videos I would suggest CC-BY-SA 4.0
[0].

What do you think? Does every contributor agree to that?
