+
+##Abstract
+
+This tool is used to generate a configuration source file for the Low Level CAN bus binding.
+This binding need a configuration provided as a C++ source file.
+As long this binding is based on [OpenXC vi-firmware](https://github.com/openxc/vi-firmware), this generator use the JSON format from the [python generator](https://github.com/openxc/openxc-python).
+The reference documentation of the JSON file can be found [here](https://github.com/openxc/vi-firmware/blob/master/docs/config/reference.rst).
+
+## Getting started
+### Build requirements
+
+* CMake version 3.0 or later
+* G++, Clang++ or any C++11 complient compiler.
+* Boost
+ * filesystem
+ * program_options
+ * system
+
+You can install any of these using your package manager. For instance, inside the iotbzh's docker image, you must enter this command :
+
+ devel@bsp-devkit:~/$ sudo apt-get install cmake libboost-system-dev libboost-filesystem-dev libboost-program-options-dev
+
+You may want to install `libboost-all-dev` to get all boost components even if it's not required.
+

+
+## Generate your config file
+
+To generate your config file you just have to run the generator using the `-m` option to specify your JSON file.
+<pre>
+<b>devel@bsp-devkit:~/projects/can-config-generator/build(master)$</b> can-config-generator -m ../tests/basic.json -o configuration-generated.cpp
+</pre>
+
+If you omit the `-o` option, then code is generated on the stdout.
+You also can specify a header and a footer file.
+These files must be valid C++ fragment as long as they will be inserted as is.
+Use the `-h` option to display help.
+
+## Supported OpenXC items
+
+As long as the low level CAN signaling binding doesn't fully support OpenXC yet, this generator is also limited.
+For instance, `initializers`, `loopers`, `buses`, `commands` and `handlers` nodes are ignored for now.
+This generator will follow OpenXC support status of the low level CAN signaling binding.
+
+## Known issues
+
+* Each `diagnostic_message` must define the same `bus` as the binding will use only one bus.
