If you'd like to link to a document from within a Course overview, Lesson, Quiz, or Assignment, you can do so using the hyperlink tool in the text/WYSIWYG editor.
To upload a link to a document using the WYSIWYG editor, simply create a hyperlink by clicking on the hyperlink button ( the little link icon).
This brings up a modal. Navigate to the 'Upload' tab and click the 'Choose file' button to browse for the file on your desktop. Select the file and the click the 'Send it to the Server' button.
This uploads the file to our server and creates a link to it. Click 'OK' when you're done.
