+### About
+
+This folder contains files to build and run JerryScript on [TizenRT](https://github.com/Samsung/TizenRT) with Artik05x board.
+
+### How to build
+
+#### 1. Set up build environment
+
+* Install toolchain
+
+Get the build in binaries and libraries, [gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar](https://launchpad.net/gcc-arm-embedded/4.9/4.9-2015-q3-update).
+
+
+Untar the gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar and export the path like
+
+```
+$ tar xvf gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar
+$ export PATH=<Your Toolchain PATH>:$PATH
+```
+
+* Get the jerryscript and TizenRT sources
+
+```
+$ mkdir jerry-tizenrt
+$ cd jerry-tizenrt
+$ git clone https://github.com/jerryscript-project/jerryscript.git
+$ git clone https://github.com/Samsung/TizenRT.git tizenrt
+```
+
+The following directory structure is created after these commands
+
+```
+jerry-tizenrt
+├── jerryscript
+└── tizenrt
+```
+
+#### 2. Add jerryscript configuration for TizenRT
+
+```
+$ cp -r jerryscript/targets/tizenrt-artik05x/apps/jerryscript/ tizenrt/apps/system/
+$ cp -r jerryscript/targets/tizenrt-artik05x/configs/jerryscript/ tizenrt/build/configs/sidk_s5jt200/
+```
+
+Apply following diff in jerry-tizenrt/tizenrt/os/FlatLibs.mk.
+(The line number may differ since tizenrt is under developing.)
+
+```diff
+--- a/os/FlatLibs.mk
++++ b/os/FlatLibs.mk

++TINYARALIBS += $(LIBRARIES_DIR)$(DELIM)libjerry-libm$(LIBEXT)
++endif
++
+# Export all libraries
+```
+
+#### 3. Configure TizenRT
+
+```
+$ cd tizenrt/os/tools
+$ ./configure.sh sidk_s5jt200/jerryscript
+```
+
+#### 4. Build JerryScript for TizenRT
+
+```
+# assuming you are in jerry-tizenrt folder
+$ cd jerryscript
+$ make -f targets/tizenrt-artik05x/Makefile.tizenrt
+```
+
+#### 5. Build TizenRT binary
+
+```
+# assuming you are in jerry-tizenrt folder
+$ cd tizenrt/os
+$ make
+```
+Binaries are available in tizenrt/build/output/bin
+
+#### 6. Flash binary
+
+The official guide will be announced on [TizenRT page](https://github.com/Samsung/TizenRT).
+
+
+#### 7. Run JerryScript
+
+You can use `minicom` for terminal program, or any other you may like, but set
+baud rate to `115200`.
+
+(Note: Device path may differ like /dev/ttyUSB1.)
+
+```
+sudo minicom --device=/dev/ttyUSB0 --baud=115200
+```
