+## ACPI driver
+
+The ACPI Driver is a Linux kernel module that utilizes the hwmon
+interface to monitor the hardware. This interface is based on the sysfs
+file system, enabling reading of the real-time data about the hardware
+status.\
+The driver provides support for sensors that report values
+of temperature, fan speeds and fan PWM for CPU and GPU
+(if supported by the platform).
+
+To install this feature follow: [Dasharo ACPI README](https://github.com/Dasharo/dasharo-acpi-dkms/tree/develop).
