The Creative Commons licenses allow creators to choose how others can use their work. The most common licenses are Attribution (CC BY), which lets others distribute, remix, and build upon the work as long as they give credit to the creator, and Attribution-ShareAlike (CC BY-SA), which allows for sharing and adapting as long as the same license applies to any derivatives. The NoDerivatives license (CC BY-ND) allows sharing the original work as long as it isn't changed in any way and credit is given. The NonCommercial license (CC BY-NC) is similar but also prohibits commercial uses of the work.
