Have you ever wondered how the open source world exists? Be a part of the open source world can be the 21 century skills that you deserve?
I wrote a book in the last 7 month, free, available on GitHub (generated as pdf/mobi/epub) but also on Leanpub.
In the post Contribute to opensource: the right way – Download the book now! you can find all the links and the story why I chose to write "Contribute to Open Source: the right way".
I am open to any kind of questions, and about hacktoberfest is just a coincidence the release of this book :-)
