CC license

Users of this sounds: Do not forget to include a link to the CC licenses in the software where it is used!

Obviously for CC-BY you have to include more (also in the program where you use it!):

• the author (which is also forgotten in this repo; preferable with a link of course, but I don't know whether that's required)
• what changes where made

And the best is also to link to work (original site where you've downloaded it - if one contributor here is the creator you may just link to this repo. Again I do not know whether this is required by CC-BY 4.0.

You can find the best practises here: https://wiki.creativecommons.org/wiki/Best_practices_for_attribution

Another thing which should be done is to make the visitors of this repo aware that they have to do the same. This can be done with a Readme.
