+Requirements
+============
+This project uses CMake [1] to create a Visual Studio project from the 
+source files. 
+
+It have been tested with:
+
+- Microsoft Visual C++ 2008 Express Edition, with SP1 [2]
+- LibUsb-Win32 0.1.12.2 [3]
+- NSIS 2.45 (to create Windows installer) [4]
+
+On Windows XP SP3.
+
+Compilation
+===========
+
+CMake can be used to create MSVC project files, then each MSVC can 
+be used to compile the project, create an installer, etc.
+
+MSVC project will create a shared library for Windows (nfc.dll), and
+a library file (nfc.lib) to link your applications against. It will compile
+examples against this shared library. Installer will install the DLL file 
+in the same directory as the examples if your goal was to be able to 
+run and install libnfc as a standard user. In a system wide installation
+the DLL should be placed in "windows\system32" or any other directory in 
+Windows PATH.
+
+If you want your own tools to use libnfc you have to link them with "nfc.lib"
+which can be found in "lib" subdirectory under the installation root. Headers 
+can be found in "include" subdirectory.
+
+In a "normal" Windows install this would be:
+- "C:\Program Files\libnfc-x.x.x\lib"
+- "C:\Program Files\libnfc-x.x.x\include"
