 # DS18B20 sensor example
 
-This example shows how to use the DS18B20 component.
+This example shows how to use the 1-Wire temperature sensor [DS18B20](https://www.analog.com/media/en/technical-documentation/data-sheets/ds18b20.pdf) component.
 
 ## How to use the example
 
+To add the component latest version to a project, you can use the following command:
+
+```bash
+idf.py add-dependency "espressif/ds18b20"
+```
+
+To create a new project from this example, use:
+
+```bash
+idf.py create-project-from-example "espressif/ds18b20:ds18b20-read"
+```
+
 ### Hardware Required
 
-* An ESP development board
-* An DS18B20 sensor connected to GPIO 18. To use a different pin, modify `EXAMPLE_ONEWIRE_BUS_GPIO` in ds18b20-read.c.
+* An ESP development board with RMT peripheral (e.g ESP32, ESP32-C3, ESP32-S3, etc)
+* An DS18B20 sensor connected to GPIO 18. To use a different pin, modify `EXAMPLE_ONEWIRE_BUS_GPIO` in *ds18b20-read.c* file.
 * An USB cable for power supply and programming
