+# libkms++ - C++ library for kernel mode setting
+
+libkms++ is a C++11 library for kernel mode setting.
+
+Also included are simple test tools for KMS and python and lua wrappers for libkms++.
+
+## Dependencies:
+
+- libdrm
+- SWIG 3.x (for python & lua bindings)
+- Python 3.x (for python bindings)
+- Lua 5.x (for lua bindings)
+
+## Build instructions:
+
+```
+$ mkdir build
+$ cd build
+$ cmake ..
+$ make -j4
+```
+
+## Cross compiling instructions:
+
+Directions for cross compiling depend on your environment. These are for mine (buildroot):
+
+As above, but specify `-DCMAKE_TOOLCHAIN_FILE=<path>/your-toolchain.cmake` for cmake, where your-toolchain.cmake is something similar to:
+
+```
+SET(CMAKE_SYSTEM_NAME Linux)
+
+SET(BROOT "<buildroot>/output/")
+
+# specify the cross compiler
+SET(CMAKE_C_COMPILER ${BROOT}/host/usr/bin/arm-buildroot-linux-gnueabihf-gcc)
+SET(CMAKE_CXX_COMPILER ${BROOT}/host/usr/bin/arm-buildroot-linux-gnueabihf-g++)
+
+# where is the target environment
+SET(CMAKE_FIND_ROOT_PATH ${BROOT}/target ${BROOT}/host)
+
+SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM ONLY)
+SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
+SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
+```
+
+## Build options
+
+You can use the following cmake flags to control the build. Use `-DFLAG=VALUE` to set them.
+
+Option name | Values | Default
+-------------------- | ------------- | --------
+CMAKE_BUILD_TYPE | Release/Debug | Release
+LIBKMS_ENABLE_PYTHON | ON/OFF | ON
+LIBKMS_ENABLE_LUA | ON/OFF | ON
