 ## What it does
 
-This script is intended to be used as part of the device production process.
-It collects a device's unique ID, displays it, stores it in a CSV file (along with a timestamp and the operator's name), and makes it available to a label printer.
+The goal is to read a device's unique ID via UART, display it, log it in a CSV file (along with a timestamp and the operator's name), and print it via a label printer. This is a typical step of a device's production process. The unique ID is stuck on the device to help an installation technician know which device is which.
 
-If the device would be a 1-Wire sensor, the device ID would be the sensor's unique 1-Wire bus address.
+If the device is a 1-Wire sensor, the device ID would be the sensor's unique 1-Wire bus address.

 ## Interaction with Arduino
+
 * Default serial port configuration: 115200 8N1 (`serial_baud_rate`)
 * Default read timeout: 2 seconds (`serial_timeout_read`)
 * Default command to query Arduino for device: `print_id` (`serial_cmd`)
 * This script expects the first 16 characters of the Arduino's response to be the device ID. Everything that follows the first 16 characters is ignored.
 
 
 ## Milestones
-* [X] Basic user interaction
+
+* [X] Straightforward user interaction
 * [X] Write CSV file
 * [X] Working serial communication
-* [ ] Print the device ID on a label printer
+* [ ] Print the device ID via a label printer
 * [ ] Take care of the `TODO` and `FIXME` code annotations
