* make it freely available, * allow people to make/suggest small changes (there is no formal editing and things may have slipped through) * allow people to covert it into various niche ebook formats * allow people to submit translations * allow people to create derivative works, such as taking out Azure specific and adding AWS specifics (I also am aware that people may not be interested enough to do any of those things)

What I am looking for is a license that allows people to make use of it, rework it, but not create a derivative work that they sell to a publisher (making it commercial). I can't necessarily limit it to pure 'non commercial' as people may 'sell' the book to cover printing costs, as I intend to do on Amazon. I would like to retain cover reference to the original authors too, but it is not a deal breaker.

I'd like some advice on a license to choose as it should be in place when I do my first commit. Should I go with a Creative Commons (Attribution-NonCommercial-ShareAlike) or is there a better alternative from the software world, like the [GNU Free Documentation License](http://www.gnu.org/copyleft/fdl.html)? Should I drop the non-commercial, as it may be too much hassle? The GNU license seems to allow for 'compensation in exchange for copies'
