Instructions are beyond worthless

This would be a 5-star review if this plugin did any of the things it is claimed to be able to do. After doing the setup no widget or buttons appeared anywhere in the website. The instructions called for pasting some javascript but gave no clue about where or in what file to paste the script! Instructions on what file to put the widget in or where in the theme were similarly missing. Clearly, neither this plugin nor its documentation had been tested before the plugin was released.
