The Perfecto module is for themers. It allows compositions to be floated over web page to quickly and accurately calibrate theme CSS. This way one doesn't have to switch between browser and Photoshop all the time to compare your current web and the end results.
After installation you have to upload your composition. You can either:
click on the link in infobox that'll show up always when there's no compositions uploaded,
move your mouse to top right corner of the browser viewport where a popup will show up (click on the link),
choose Perfecto from the admin menu,
go to url admin/settings/perfecto.
