The Submission settings is where you enter instructions for users. You also set limits on how many files students can upload in the workshop and how large these files can be. This is where you partially answer the question, that is, what will you have each student do? The following is the screenshot of Submission settings:

The user will see the Instructions for submission label when they click on the workshop.

Maximum number of submission attachments and Maximum submission attachment size determine the size of a file and how many files the user can upload.

Late submissions allow users to submit their work after the deadline. The deadline is set further down the page.

It is a good idea to encourage students to upload their work to the cloud and then provide a link. For example, this can work with presentations in Screencast-o-matic, or in a video on YouTube. This will help students avoid hitting the file size limit.
