## What is in this book

**Assembly** takes a device from a sealed box to a powered, wired unit on a
weighing scale.

**Configuration** is everything that happens before a device is useful: what
the Wi-Fi network has to provide, the three ways to hand a device its
credentials, and scanner setup.

**Operation** is the day-to-day - the keypad, PLU updates, firmware updates
over the air, and finding a device on the network.

**Troubleshooting** is arranged by symptom rather than by cause, because a
symptom is what the person reading it has.
