The Learning Package course element-type is where you will upload any of your packaged content such as SCORM files, AICC files, xAPI, files, or even PowerPoint (see PowerPoint article for all of your options).

Learning packages are self-contained pieces of content that can be created and edited outside of DigitalChalk by tools like Dominknow, Articulate Storyline, etc., and then slotted into your course. They allow for media-rich presentations and are standardized across many LMS platforms. Make sure to upload the .zip file of your package.
