+## Cyper Power PDU remote control
+
+This is a command wrapper around net-snmp-utils, you need to install
+these command line utility first. To use this software:
+
+./cyberpdu <pdu-ip> <socket-name> (on|off|reset)
+
+The name are configured form the Web UI and the reset delay is also 
+configured there.
+
+## TODO
+
+- Allow socket number to be used
