This template uses the whatsnote class, an elegant layout with tools for taking notes in science, engineering and similar fields. The eight-page demo introduces the package and includes a coordinate grid for sketching, Font Awesome icons through fontawesomescaled, and the duckuments package for sample content. It is suited to class notes, lab books and study summaries. Replace the sample content with your own and compile to see the result.
