those authorized to give the public permission to use material in ways otherwise
restricted by copyright and certain other rights. Our licenses are irrevocable.
Licensors should read and understand the terms and conditions of the license
they choose before applying it. Licensors should also secure all rights necessary
before applying our licenses so that the public can reuse the material as

Considerations for the public: By using one of our public licenses, a licensor
grants the public permission to use the licensed material under specified
terms and conditions. If the licensor's permission is not necessary for any

grant. Use of the licensed material may still be restricted for other reasons,
including because others have copyright or other rights in the material. A
licensor may make special requests, such as asking that all changes be marked

requests where reasonable. More considerations for the public : wiki.creativecommons.org/Considerations_for_licensees
