FAQ

Does this apply to wikis and encyclopedias? Yes. The term "Work" covers articles, documentation, educational material, and any text-based creative content.

Can I use this in a commercial book? Yes. You may sell, publish, or include the work in commercial products, as long as you attribute and share adaptations under the same license.

What if I only use a small excerpt? Fair use and fair dealing exceptions still apply. The license only governs uses that require permission under copyright law.

Can I dual-license? The license text does not explicitly allow dual-licensing. If you need that, consider using a standard license or adding a specific clause.
