Author : roshan.gonsalkorale@oracle.com, alex.wilton@oracle.com, mike.knott@oracle.com

Debugger:
	
- add 'bk_so_logger=true' as a query-string parameter in the URL and check the console logs

Implementation Instructions:

- Third party specific instructions:
	- DFP - DFP to be implemented via Google Publisher Tag (https://developers.google.com/doubleclick-gpt/)
- Update the config as per the "CONFIG" section below (please reach out to Oracle for help if required)
