Hello @hernaame1979
Thank you for contacting the Instructure Community. Welcome to Canvas - we're here to help. Your assignment is likely just that - an assignment that you will write and work on outside of Canvas and then upload to the course. The instructions of your specific assignment are important in assisting you, but if you have specific questions about the details your instructor has given you or need help possibly with a tutor - it would be best to speak with you instructor or school directly to set this up and get the proper help you are looking for.
Canvas courses can be set up in a number of ways, but you will likely use "modules" tab on the left navigation along with other common tabs like assignments, discussions, syllabus, etc. Try to move through in order. When you need to actually submit the assignment, this guide should be helpful:
