Giving credit to sources

Some discovery content comes from Wikipedia and related Wikimedia projects. That text is usually free to reuse under a Creative Commons Attribution-ShareAlike licence (CC BY-SA 4.0), which means you should credit the source and keep a similar licence if you share material that includes it. Extra terms can apply. If you only use KeywordCracker privately to brainstorm keywords, you typically do not need to republish Wikipedia text at all.
