The simplest assignment requires the upload of a single file. The assignment will appear in your Moodle course as with the text varying according to the assignment.

1. Click on the link for the assignment.
2. Click Add Submission.
3. Drag-and-drop your file into the upload box, or use the "Add file" button to choose it.
   
4. Once that is done, click on Save changes to actually upload the file.
5. Your assignment interface will now show the name of the file you uploaded and, if the instructor has set the assignment to allow it, the Upload a file button will have changed to Update this file which allows you to replace the file with a new one.

Remember that Assignments pass information between you and the instructor. Uploaded assignment files are not visible to other students.
