+
+## Info
+### Send RC codes
+
+Use your Arduino or Raspberry Pi to operate remote radio controlled devices.
+This will most likely work with all popular low cost power outlet sockets. If
+yours doesn't work, you might need to adjust the pulse length.
+
+All you need is a Arduino or Raspberry Pi, a 315/433MHz AM transmitter and one
+or more devices with one of the supported chipsets:
+
+ - SC5262 / SC5272
+ - HX2262 / HX2272
+ - PT2262 / PT2272
+ - EV1527 / RT1527 / FP1527 / HS1527 
+ - Intertechno outlets
+ - HT6P20X
+
+### Receive and decode RC codes
+
+Find out what codes your remote is sending. Use your remote to control your
+Arduino.
+
+All you need is an Arduino, a 315/433MHz AM receiver (altough there is no
+instruction yet, yes it is possible to hack an existing device) and a remote
+hand set.
+
+For the Raspberry Pi, clone the https://github.com/ninjablocks/433Utils project to
+compile a sniffer tool and transmission commands.
