Creative Commons is a non-profit organisation that helps authors and creators share their work, by providing free, simple and standardised ways to let others copy, distribute and make use of those works, while still maintaining copyright
Creative Commons licences let you fine-tune what rights you retain while letting others use your work.
There are several different elements that can be combined together to create Creative Commons licenses that have different permissions. The elements are:
- BY - Requiring attribution
- NC - Non-commercial only
- ND - No modification of the work
- SA - Modifications of the work can only be shared with the same CC licence
What elements you use will depend on what you want to do with with your work
