Todos are really checklists that allow you to show tasks that have been completed.
[x] Make breakfast

Additional paragraph.
A todo is wrapped in a div with a class of todo. Inside there is an input[type=checkbox] which will have its checked value set if the item is checked. The checkboxes will be marked with the readonly attribute.
The text of the todo is in a p element. If there is additional content, it will be following the p element.
