-         This driver uses ACPI INT3403 device objects. If present, it will
-         register each INT3403 thermal sensor as a thermal zone.
+         Newer laptops and tablets that use ACPI may have thermal sensors
+         outside the core CPU/SOC for thermal safety reasons. These
+         temperature sensors are also exposed for the OS to use via the so
+         called INT3403 ACPI object. This driver will, on devices that have
+         such sensors, expose the temperature information from these sensors
+         to userspace via the normal thermal framework. This means that a wide
+         range of applications and GUI widgets can show this information to
+         the user or use this information for making decisions. For example,
+         the Intel Thermal Daemon can use this information to allow the user
+         to select his laptop to run without turning on the fans.
