... All of the content in this site is completely open source, and we welcome your contribution. Whether you notice a small improvement that should be made, or want to write entirely new articles, this is one area where feature requests are encouraged!
... Each of our articles has a link to the raw content on GitHub, and we urge everyone to fork, edit, and help improve this community resource!" - from source: http://learn.jquery.com/
