 ## Usage
 To begin, right-click (control-click for Mac) on the collection you wish to analyze and select "Extract Texts for Paper Machines." Once the extraction process is complete, this right-click menu will offer several different processes that may be run on a collection, each with an accompanying visualization. Once these processes have been run, selecting "Export Output of Paper Machines..." will allow you to choose which visualizations to export.
