 Module that connects to ZEDO's demand sources.
 
+ZEDO supports both display and video. 
 For video integration, ZEDO returns content as vastXML and requires the publisher to define the cache url in config passed to Prebid for it to be valid in the auction
 
+ZEDO has its own renderer and will render the video unit if not defined in the config.
