The guided setup walks you through seven steps in order: Company profile, Depot, Driver, Vehicle, Customer, Rates and First booking. On each step it opens the right page, points an arrow at the button to press and moves on by itself when the step is done.
You can press Back, Skip setup or Do it later. If you hide it, a small "Setup 3/7" pill at the bottom of the screen lets you carry on; after Skip setup, press Resume setup on the dashboard to start again.
