Sure. The Creative Commons licenses provide several copy and share licenses complete with legal code, computer code, and a human-readable declaration and graphic to let others know that they’re invited to copy and share. You can choose whether to require attribution, permit commercial use, or allow modifications.
If someone wants to do more than is permitted by fair use or the terms of your license, they can still contact you for permission. See Creative Common’s licensing page for more information, or generate your own license.
