Creative Commons (CC) is the forefront [non-profit](non_profit.md) organization promoting [free culture](free_culture.md), i.e. basically relaxation of ["intellectual property"](intellectual_property.md) (such as [copyright](copyright.md)) in [art](art.md). One of the most important contributions of the organization are the widely used Creative Commons [licenses](license.md) which artists may use to make their works more legally free and even put them to the [public domain](public_domain.md).
Creative commons [licenses](license.md)/waivers form a **[spectrum](spectrum.md)** spanning from complete freedom (CC0, [public domain](public_domain.md), no conditions on use) to complete [fascism](fascism.md) (prohibiting basically everything except for non-commercial sharing). This means that **NOT all Creative Commons licenses are [free cultural](free_culture.md) licenses** -- this is acknowledged by Creative Commons and has been intended. Keep in mind that as a good human you mustn't ever use licenses with [NC](nc.md) (non-commercial use only) or [ND](nd.md) (no derivatives allowed) clauses, these make your work non-free and therefore unusable.
