+Host power control
+------------------
+
+The host can be controlled through the `chassis` object. It implements a number
+of actions including powerOn and powerOff. These correspond to the IPMI
+`chassis power on` and `chassis power off` commands.
+
+Assuming you have logged in, the following will issue a POST with an empty data
+payload that powers the host on:
+
+```
+curl -c cjar -b cjar -k -H "Content-Type: application/json" -X POST \
+   -d '{"data": []}'  https://bmc/org/openbmc/control/chassis0/action/powerOn
+```
+
+Other actions available are:
+
+ * `setIdentify` / `clearIdentify`
+ * `powerOff`
+ * `softPowerOff`
+ * `reboot`
+ * `softReboot`
+ * `getPowerState`
