+Introduction
+------------
+
+Most mainboards have sensor chips to monitor system health (like temperatures,
+voltages, fans speed). They are often connected through an I2C bus, but some
+are also connected directly through the ISA bus.
+
+The kernel drivers make the data from the sensor chips available in the /sys
+virtual filesystem. Userspace tools are then used to display or set or the
+data in a more friendly manner.
+
+Lm-sensors
+----------
+
+Core set of utilites that will allow you to obtain health information,
+setup monitoring limits etc. You can get them on their homepage
+http://www.lm-sensors.nu/ or as a package from your Linux distribution.
+
+If from website:
+Get lmsensors from project web site. Please note, you need only userspace
+part, so compile with "make user_install" target.
+
+General hints to get things working:
+
+0) get lm-sensors userspace utils
+1) compile all drivers in I2C section as modules in your kernel
+2) run sensors-detect script, it will tell you what modules you need to load.
+3) load them and run "sensors" command, you should see some results.
+4) fix sensors.conf, labels, limits, fan divisors
+5) if any more problems consult FAQ, or documentation
+
+Other utilites
+--------------
+
+If you want some graphical indicators of system health look for applications
+like: gkrellm, ksensors, xsensors, wmtemp, wmsensors, wmgtemp, ksysguardd,
+hardware-monitor
+
+If you are server administrator you can try snmpd or mrtgutils.
