I want to add plugin "pdi-google-spreadsheet-plugin-master" to pentaho's Kettle Spoon. I have download "pdi-google-spreadsheet-plugin-master" and unziped it to "C:\Pentaho\data-integration\plugins" but I don't know from where I can use this plugin in kettle spoon. I have also tried to copy that "D:\Pentaho\data-integration\plugins\steps", but unable to see or find how to use that plugin in transormation or in jobs.
Thank you
