!! Selecting this option does NOT download your package - you will still need to return to the Assembler and select either Download zip or Save to Cloud to do that!
To test out your package and see how it will appear in a learning management system, click on the Preview button.
This will launch the Preview in an overlay frame, where your course package will be uploaded for testing. You can then play the course and see how it works from a user's perspective.
After you close the Preview, you can still switch back to the Course Assembler to make more changes and preview again - the files are not "wiped" from your browser until you press the Reset link.
