There are a number of ways to kick start your first user flow in Overflow. You can iterate upon a sample flow, sync your Sketch artboards to a new Overflow document, insert screens from Figma, or start off with a blank one and build with basic images & shapes. After rearranging your elements and think you're ready to go, starting connecting them to build your first user flow.
Boards are extremely useful to organize your flow into smaller sub-flows and building alternative or extra flows. You can go wild and create a Board just to experiment with things you'd never imagine doing. Don't worry though, you can hide them from Presentation and in the Share link.
The Boards menu is found on the left of your window, where you can create, rename, delete, hide/show, export and rearrange boards. You can also change the board's background color.

If you like viewing user flows as a whole, you'll probably enjoy the Navigator Map (toggle with 'N') which will give you an indication of your entire flow relative to your current view.
