+# Monkey + Arduino YUN toolchain
+
+Short instructions to build with Arduino YUN toolchain:
+
+## Get the toolchain
+
+```shell
+$ git clone https://github.com/MatteoRagni/ArduinoYun-x86_64-OpenWRT-mips-linux-toolchain.git
+```
+
+The content downloaded is the toolchain required, the absolute path of this directory is required in the next step:
+
+### Compile Monkey
+
+Make sure to replace the right values for CMAKE_INSTALL_PREFIX and _YUN_ROOT_:
+
+```
+$ rm -rf monkey/build
+$ cd monkey/build
+$ cmake -DCMAKE_TOOLCHAIN_FILE=cmake/arduino-yun.cmake \
+        -DWITH_SYSTEM_MALLOC=ON -DWITH_BACKTRACE=OFF   \
+        -DCMAKE_INSTALL_PREFIX=/opt/monkey             \
+        -DYUN_ROOT=/path/to/ArduinoYun-x86_64-OpenWRT-mips-linux-toolchain \
+        ../
+$ make
+$ make install
