 ### License Setup (Don't Skip This!)
 
-Here's something that trips up a lot of developers: GroupDocs.Comparison requires a license for production use. For development and testing, grab a temporary license – it's free and removes all the evaluation watermarks that'll otherwise appear in your output.
