+Overview
+========
+The Hello World demo application provides a sanity check for the new SDK build environments and board bring up. The Hello
+World demo prints the "Hello World" string to the terminal using the SDK UART drivers. The purpose of this demo is to
+show how to use the UART, and to provide a simple project for debugging and further development.
+
+Toolchain supported
+===================
+- GCC RISC-V Embedded 7.1.1
+- RISC-V Eclipse IDE 4.7.2
+
+Hardware requirements
+=====================
+- Mini/micro USB cable
+- RV32M1-VEGA board
+- Personal Computer
+
+Board settings
+==============
+No special settings are required.
+If download M0+ core project, need to let MCU boot from M0+ core, please follow below steps:
+1. Download blhost.exe from www.nxp.com/kboot.
+2. Connect J8 on board to PC using USB cable.
+3. After PC recognize the USB HID device, go to blhost.exe folder, open command line.
+4. Run command "blhost.exe -u -- flash-erase-all-unsecure", it will erase the flash on chip.
+5. Run command "blhost.exe -u -- flash-program-once 0x84 4 ffffffbf", set FOPT3 to boot from M0+ core.
+
+Prepare the Demo
+================
+1. Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
+2. Open a serial terminal with the following settings:
+ - 115200 baud rate
+ - 8 data bits
+ - No parity
+ - One stop bit
+ - No flow control
+3. Download the program to the target board.
+4. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
