-This is a fork from **http://tmrh20.github.io/RF24Network** which can be build as a static library for Atmel Studio 7.
+# TMRh20 2014 - Newly Optimized Network Layer for nRF24L01(+) radios
 
-Not all files are needed.
+Please see the full documentation at http://tmrh20.github.io/RF24Network/
 
-Just copy the following structure into a GCC Static Library project in AS7:
 
-```
-RF24Network.cpp
-RF24Network.h
-RF24Network_config.h
-Sync.cpp
-Sync.h
-```
+## Raspberry Pi - PreConfig
+
+### Possible pre-configuration:  
+If SPI is not already enabled, load it on boot:   
 
-Only ATXMega256D3 is supported right now!
+    sudo raspi-config  
 
-** For further information please see http://tmrh20.github.io/RF24Network for all documentation**
+A. Update the tool via the menu as required  
+B. Select Advanced and enable the SPI kernel module      
+C. Update other software and libraries:  
+
+     sudo apt-get update  
+     sudo apt-get upgrade  
+
+# RPi - RF24 Quick-Start  
+     
+A. Make a directory to contain the RF24 and possibly RF24Network lib and enter it:  
+
+    mkdir ~/rf24libs  
+    cd ~/rf24libs  
+
+B.  Clone the RF24 Repo  
+
+    git clone https://github.com/tmrh20/RF24.git RF24  
+
+C.  Change to the new RF24 directory    
+
+    cd RF24  
+
+D. Build the library, and run an example file:  
+
+    sudo make install
+    cd examples_RPi  
+    make  
+    sudo ./gettingstarted  
+
+
+# RPi - RF24Network Quick-Start  
+
+A. Enter the same directory that contains the RF24 library folder  
+
+    cd ~/rf24libs  
+
+B. Clone the RF24Network Repo  
+
+    git clone https://github.com/tmrh20/RF24Network.git RF24Network  
+
+C. Copy the RF24Network folder to the current directory, and delete the rest  
+
+    cd RF24Network  
+
+D. Build the library  
+
+    sudo make install
+    cd examples_RPi  
+    make  
+    sudo ./helloworld_rx   OR   sudo ./helloworld_tx  
+
+
+# Connection Info
+
+Using pin 15/GPIO 22 for CE, pin 24/GPIO8 (CE0) for CSN
+
+Can use either RPi CE0 or CE1 pins for radio CSN.
+Choose any RPi output pin for radio CE pin.
+
+**Constructor:**
+
+    RF24 radio(RPI_V2_GPIO_P1_15,BCM2835_SPI_CS0, BCM2835_SPI_SPEED_8MHZ);
+    or
+    RF24 radio(RPI_V2_GPIO_P1_15,BCM2835_SPI_CS1, BCM2835_SPI_SPEED_8MHZ);
+
+	RPi B+:
+	RF24 radio(RPI_BPLUS_GPIO_J8_15,RPI_BPLUS_GPIO_J8_24, BCM2835_SPI_SPEED_8MHZ);
+	or
+	RF24 radio(RPI_BPLUS_GPIO_J8_15,RPI_BPLUS_GPIO_J8_26, BCM2835_SPI_SPEED_8MHZ);
+
+**Pins:**  
+

+See http://www.airspayce.com/mikem/bcm2835/index.html for BCM2835 class documentation.  
+Note: The BCM library has been customized slightly to allow use of hardware CE pins not
+in use for SPI, and to include a millis() function.

+****************
+
+Based on the arduino lib from J. Coliz <maniacbug@ymail.com>.  
+the library was berryfied by Purinda Gunasekara <purinda@gmail.com>.  
+then forked from github stanleyseow/RF24 to https://github.com/jscrane/RF24-rpi  
+Network lib also based on https://github.com/farconada/RF24Network
+
+Currently optimized and aligned with Arduino fork of libraries by TMRh20:  
+https://github.com/tmrh20/RF24/RPi and https://github.com/tmrh20/RF24Network/RPi
