+# Example Thermald Configuration
+
+This is a minimal thermald configuration, which sets the maximum sustained CPU temperature to about 65°C.
+Modify the `<Temperature>65000</Temperature>` value to adapt that to your liking.
+
+Tested on a Surface Book 2, other devices may need adapting, see e.g. the [thermald man page](http://manpages.ubuntu.com/manpages/trusty/man5/thermal-conf.xml.5.html).
+
+## Installation
+
+Both XML files need to be placed in the `/etc/thermald/` directory.
+
+Newer thermald versions attempt to automatically load the configuration from ACPI.
+If you want to use a manual configuration with such a version, you may need to remove the `--adaptive` option from the systemd service `ExecStart` line.
+You can do so by running `sudo systemctl edit thermald.service`.
