+                      Cypress Semiconductor Corporation
+                            CyUSB Serial library.
+=========================================================================================
+Pre-requisite:
+1. libusb-1.0.9 is required for compilation and functioning of the APIs in the library.
+2. GNU Make and the GCC tool-chain are used for the build process.
+
+Installation steps:
+
+1.cd to the main directory where the library source files are extracted and goto ./linux/library
+
+2.Type 'sudo make'.
+
+2.This will generate shared library libcyusbserial.so.1 and its soft link libcyusbserial.so.
+  Both of them will be copied/installed to /usr/local/lib.
+
+3.Go to ./linux/testUtility (I2C/SPI test utility program) and type 'sudo make'. 
+This will generate CyUSBSerialTestUtility binary (Refer to README in testUtility folder).
+
+4.User can launch the application and test the communication with Cypress USB-Serial DVk in vendor mode.
+
+Changing USB device node permission:
+
+By default the USB device node created in linux do not have read/write permission
+for normal user. In order to make the USB device node accessable, copy 90-cyusb.rules
+which is inside the library folder of release package to /etc/udev/rules.d folder (Default VID mentioned is Cypress VID
+which is 0x4B4, if VID is changed then update it in ATTR{idVendor} section of rules file).
+
+*** IMPORTANT:
+Some distribution of linux have libusb (older version) as part of their package. Uninstall 
+the older version and update it with libusb-1.0.9.
+
+**Note:
+Refer to ./common/doc/CyUSBSerial API documentation.pdf for description of all
+the vendor mode APIs. The header file of the library is in ./common/header/CyUSBSerial.h.
