We open in three days. Is that enough time to be ready?

Yes, if your menu is written down somewhere. A realistic run is menu and prices on day one, hours, delivery areas and WhatsApp on day two, the counter on day three. Pairing a device and adding people takes about ten minutes. The slow part is always typing the menu, so upload it from a spreadsheet if you have one. Settings, Getting started is the same checklist inside your dashboard.
