TL;DR
Keep instructions, links and files with the task they support. Personal notes on a teacher assignment do not rewrite its original instructions.
Add supporting information
Open a task you can edit.
Enter your notes in its notes area. Use short headings or a checklist to make the next action clear.
Use the attachment controls to add a supported file, image or link.
Save, then reopen the task and test the attachment.
For a class-period note, select the period and use its note action. A note records information; it does not have the same planning state as a task.
An attached link can still require permission in Google Drive, Microsoft or another service. If it will be shared, check access with the people who need it. Removing a link from Studyo does not delete the source document.
