Dashboards are combinations of sheets. To make a dashboard, you will need to have at least two sheets.
To get started, create a new dashboard by clicking the middle icon (of four squares) in the bottom toolbar, where you create new sheets. This will bring up this window:
On the left side of the screen, you will see sheet names. Drag and drop them into the center white space to begin populating your dashboard. Once you place your sheets, you can add text and images (like titles, or photos of Beyoncé) to your dashboard by dragging and dropping the "Text" and "Image" boxes you see in the "Objects" panel in the bottom left of the screen.
