+this is library to use the nrf24l01 on the raspberry pi.
+
+it's based on the arduino lib from J. Coliz <maniacbug@ymail.com>.
+the library was berryfied by Purinda Gunasekara <purinda@gmail.com>.
+then forked from forked from github stanleyseow/RF24 by myself
+
+setup the library
+=================
+
+Clone or download this repo then go to folder
+cd RF24/librf24-rpi/librf24-bcm/
+
+then 
+
+make ; make install
+
+examples
+========
+
+go to examples subfolder then 
+make ; make install
+
+In my examples I used the NRF on ArduiPi Board 
+http://hallard.me/arduipi
+
+So on example file the instance is created as follow, change the pins according your connections
+
+// Setup for GPIO 22 CE and CE1 CSN with SPI Speed @ 8Mhz
+RF24 radio(RPI_V2_GPIO_P1_15, RPI_V2_GPIO_P1_26, BCM2835_SPI_SPEED_8MHZ);  
+
+
+Pin are
+NRF24L01    RPI       P1 Connector
+nrf-vcc  = rpi-3v3        (01)
+nrf-gnd  = rpi-gnd        (06)
+nrf-ce   = rpi-ce1        (26)
+nrf-csn  = rpi-gpio22     (15)
+nrf-sck  = rpi-sckl       (23)
+nrf-mo   = rpi-mosi       (19)
+nrf-mi   = rpi-miso       (21)
