Quick start

  1. Flag a note as a project. Add marktodo: true to its frontmatter. Status headings in that note now stay in sync with your todos.
  2. Write a todo. Anywhere in the note, type - [ ] Call the plumber.
  3. Act on it. Click the checkbox, or open the MarkTodo dashboard from the ribbon, pick the project, and drag the todo to another status. The line in the note changes.
  4. Add a due date. Type due @ 2026-07-01 on the line, wherever you like.
  5. Open it on your phone. The app reads the same file.

Todos in notes that are not projects are loose. You can still check them off, and they wait in the Inbox until you move them somewhere.
