+
+##	Introduction 
+
+The aim of this project is to help users set up a LoRa network easily. The User Guide can be get from our Web.
+
+##	Supported platforms
+
+This project currently provides support for the below platforms.
+* RAK831
+* RAK833
+* RAK2245
+* RAK2247
+* RAK7243
+
+##	Changelog
+
+2019-05-24 V2.9
+
+* 1.Multiple models are integrated with one common version.
+* 2.Upgrade LoRa server to 3.0.
+
+##	Installation procedure
+
+step1 : Download and install [Raspbian Stretch LITE](https://www.raspberrypi.org/downloads/raspbian/) 
+
+step2 : Use "sudo raspi-config" command, enable spi and i2c interface.
+
+step3 : Clone the installer and start the installation.
+
+      $ sudo apt update; sudo apt install git -y
+      $ git clone https://github.com/RAKWireless/rak_common_for_gateway.git ~/rak_common_for_gateway
+      $ cd ~/rak_common_for_gateway
+      $ sudo ./install.sh
+
+step4 : Next you will see some messages as follow. Please select the corresponding hardware model.
+
+      Please select your gateway model:
+      *	1.RAK831
+      *	2.RAK833
+      *	3.RAK2245
+      *	4.RAK2247
+      *	5.RAK7243
+      Please enter 1-5 to select the model:
+
+step5 : Wait a moment and the installation is complete.If your gateway uses a wired connection, please reconfigure the LAN's IP address using "sudo gateway-config" after the installation is complete.
+
+step6 : For more other features, please use "sudo gateway-config".

+    Single-byte read/write and burst read/write.
+    Does not handle pagination.
+    Could be used with multiple SPI ports in parallel (explicit file descriptor)

+# * password - The user's password
+# * host - The host to connect to. Values that start with / are for unix domain sockets. (default is localhost)

+# * connect_timeout - Maximum wait for connection, in seconds. Zero or not specified means wait indefinitely.
