Good morning, @Wjohnson4 ...
Could you please provide some additional details to your question? First, are you an instructor or a student? What kind of content are you looking to upload and/or link? Is the content just text with some pictures/images? Something else? What kind of external content are you looking to link? Any additional information from you will be helpful so that Community members know how best to assist you and give you the info you're looking for.
Looking forward to hearing back from you soon! Take care, and be well...
