+Introduction
+============
+
+The Genio 1200-Demo (mt8195-demo) board is featuring the MediaTek
+MT8195/MT8395 Family SoC.
+
+Genio 1200-Demo board features:
+	* CPU: ARMv8 64bit Big-Little architecture,
+		* Big: quad-core Cortex-A73
+		* Little: quad-core Cortex-A53
+	* DRAM: 2x 4GB dual-channel
+	* eMMC: onboard eMMC
+	* SD/MMC
+	* GbE (onboard RTL8211F) Gigabit ethernet PHY
+	* PCIE: 2-lane M.2 E-Key
+	* USB:
+		* USB3.0 dual role port
+		* 1x USB3.0 host, 2x USB2.0 host
+	* Display: HDMI/eDP/MIPI
+	* Camera: 3x 4-lane CSI
+	* APU
+
+Here is the step-by-step to boot to U-Boot on Genio 1200-Demo (mt8195-demo)
+board.
+
+Get the Source from Genio IOT Yocto
+===================================
+
+To download the Genio IOT Yocto source code, please follow the instructions
+in [1]. With the full source code, developers can easily build the boot chain,
+which includes components such as TF-A, u-boot, kernel, and the complete
+Genio IOT Yocto image.
+
+Compile the U-Boot
+==================
+
+Linux native build with latest U-Boot.
+
+  > cd u-boot
+  > make CROSS_COMPILE=aarch64-linux-gnu- mt8195_demo_defconfig all
+
+Genio IOT Yocto build with latest U-boot or Genio IOT Yocto's U-boot.
+
+  > DISTRO=rity-demo MACHINE=i1200-demo bitbake u-boot
+
+Genio IOT Yocto build TF-A and package U-boot into bl31 together.
+
+  > DISTRO=rity-demo MACHINE=i1200-demo bitbake trusted-firmware-a
+
+Flash the image
+===============
+
+MediaTek currently support the use of the Genio IOT Yocto toolset with the
+'genio-flash' USB download tool for flashing images. To install 'genio-flash',
+use Python's 'pip' package manager. Then, follow the instructions provided
+in [2] to flash u-boot with the IOT Yocto image.
+
+   > pip install genio-flash
+
+cd into the folder contains Genio IOT Yocto image, then run 'genio-flash'.
+
+   > genio-flash
