+hp-wmi-sensors (hwmon sensors driver for HP business-class PCs)
+
+Hewlett-Packard (and some HP Compaq) business-class computers report
+hardware monitoring information via Windows Management Instrumentation
+(WMI). This driver exposes that information to the Linux hwmon
+subsystem, allowing userspace utilities like sensors to gather numeric
+sensor readings.
+
+In particular, it's required on some systems (e.g. the SlackBuild
+author's HP Z2 Mini G3) for fan speeds to be visible in 'sensors'.
+
+Slackware-specific notes:
+
+The driver is a kernel module. By default, it's built for the
+currently running kernel, but you can build it for any kernel version
+if you have that kernel's modules and source installed. Set the KERNEL
+environment variable to the version you want to build for.
+
+After installation, you can load the driver immediately, with:
+
+  /sbin/modprobe hp-wmi-sensors
+
+To load the module on every boot, add the above command to
+/etc/rc.d/rc.modules.local
+
+Note that there's already an hp-wmi module in Slackware's
+kernel-modules package. Loading hp-wmi-sensors will add new sensors,
+if there any supported by the driver. Look at the output of the
+'sensors' command before and after loading the module, to see if it
+found anything supported.
+
+Note to Slackware-current users: this build was developed and
+tested on Slackware 15.0 (latest stable) with the 5.15.x series of
+kernels. It may or may not work on -current. If it doesn't, I don't
+want you to contact me about it *unless* you send me a patch that
+fixes it.
