I just recently started my Articulate 360 trial and wanted to try converting an existing PowerPoint file to a trackable course via LMS. From reading other posts, as well as looking up how to publish the presentation for a LMS I see references to story.html, but when Studio 360 publishes the files to my hard drive, I don't see any files named "story.html". I see a lot of .html files, but which one is synonymous with story.html? index_lms.html? presentation.html?
