Everything is under Scheduling, Setup.

1. Services: add what customers can book, with a length. The price is optional; leave it empty when there is no charge.
2. People and working hours: for each person, choose their working days and hours, a daily break, which services they do, and whether customers can book them online.
3. Booking rules: the shortest notice, how far ahead people can book, whether bookings are confirmed automatically, and reminders.
4. Share your booking page: the link is at the top of Setup. Put it on your website or send it to customers.

Customers pick a service, a day and a time, and get a confirmation by email with a link to change or cancel.
