-####Possible pre-configuration:  
-  If SPI is not already enabled, load it on boot:   
-```    
     sudo raspi-config  
-```
+
 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  
-======================     
+
+
+# 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 rtemp  
-```  
+
 C.  Copy the RPi library folder to the current directory, and delete the rest  
-```
+
     mv rtemp/RPi/RF24 ./  
     rm -r rtemp  
     cd RF24  
-```  
+
 D. Build the library, and run an example file:  
-```
-    sudo make  
+
+    sudo make install
     cd examples  
-	sudo make  
+    make
     sudo ./gettingstarted  
-```  
   
-RPi - RF24Network Quick-Start  
-=============================  
+
+# 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 ntemp  
-```  
+
 C. Copy the RF24Network folder to the current directory, and delete the rest  
-```  
+
     mv ntemp/RPi/RF24Network ./  
     rm -r ntemp  
     cd RF24Network  
-```  
+
 D. Build the library  
-```
+
     sudo make  
     cd examples  
     sudo make  
     sudo ./helloworld_rx   OR   sudo ./helloworld_tx  
-```

 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
