+## Create a new Visual Studio project with the library included
+
+Download the latest version of libmodbus source code from Github
+`https://github.com/stephane/libmodbus` -> Code -> Download ZIP.
+
+Once the archive is decompressed, launch a Windows terminal (`cmd`) in
+`src/win32` directory and run `cscript configure.js`.
+
+1. copy the file `config.h` from `src/win32` to `src`.
+2. create a new 'Console App' project under Visual Studio.
+3. create a new directory called `libmodbus` inside your VS project (same level
+   as the `.vcxproj` file).
+4. copy all `*.c` and `*.h` from libmodbus `src` in the new `libmodbus` folder
+   of your VS project.
+5. copy `modbus.rc` in your VS project (same level as the `.vcxproj` file).
+6. drag and drop `libmodbus/*.c` files (4) in *Solution Explorer -> Source Files*.
+7. drag and drop `libmodbus/*.h` files (8) in *Solution Explorer -> Header Files*.
+8. drag and drop `modbus.rc` file in *Solution Explorer -> Resource Files*.
+9. check path is `#include "modbus-version.h"` in `modbus.rc`.
+10. in the **Property Pages** of the project *Configuration Properties -> C/C++
