+# Fan Monitor
+
+The fan monitor application provides the following functionality:
+
+- Sets the functional state of fan sensors in the inventory based on comparing
+  the target speed of the sensor to the actual speed.
+- Sets the functional states of fan FRUs in the inventory based on the child
+  fan sensor functional states.
+- Creates event logs for fan sensors that have been nonfunctional for too long.
+- Creates event logs for fans that have been missing for too long.
+- Can power off the system based on rules that look at the number of
+  nonfunctional fan sensors or missing fans.
+
+This is all configurable in a [JSON file](json.md).  It also supports build
+time configuration based on a [YAML file](example/monitor.yaml), though that
+doesn't support the full functionality and has been deprecated in favor of the
+JSON configuration.
