SCORM / xAPI package documentation

no - there is no documentation

you'll have to figure it out for yourself, but here are a few hints

step 1: for the storyline part - publish to web (result are all web files without the LMS files)

• story.html (the start file)
• analytics-frame.html (the articulate tracking file for "Help improve Articulate 360 ...")
• meta.xml (not used, but interesting)
• html5/lib/ ... (the javascript, css library of the player)
• html/data/css/output.min.css (all used fonts, ...)
• html/data/css/js/ (the infos for the slides, ...)
• mobile/ (images, ...) - IMPORTANT the name of the folder is wrong
• mobile/notes/ (not used anymore)
• mobile/slides/ (not used anymore)
• story_content (videos, ...)
• story_content/notes/ (not used anymore)
• story_content/slides/ (not used anymore)
• story_content/user.js (the javascript of all your javascript trigger)
• and some more

step 2: if you publish to LMS some files are added

• index_lms.html (the html start file for the LMS)
• folder "lms" with the storyline files for the communication with the LMS*
• many xml, xsd, dtd files and some folder depending on the scorm version (e.g. common/extend/unic/vocab)*

* but they are not very interesting (except lms/scormdriver.js)
