+# How to build Windows binaries
+
+## Preparation
+
+TODO...
+
+## Build with Visual C++ Express
+
+You need to use Visual C++ 2012 or later to build Mroonga with Express
+edition. `build-vc2013.bat` is a build batch script to build with
+Visual C++ Express 2013.
+
+Note that you can't build MSI file with Express edition. You need to
+use Professional edition or upper editions to build MSI file.
+
+## Build with Visual C++ Professional
+
+You can build both zip file MSI file with Professional edition.
+`build-vc2010.bat` is a build batch script to build with Visual C++
+Professional 2010.
