+WINDOWS BUILD NOTES
+====================
+
+Some notes on how to build Bitcoin Core for Windows.
+
+Most developers use cross-compilation from Ubuntu to build executables for
+Windows. This is also used to build the release binaries.
+
+Building on Windows itself is possible (for example using msys / mingw-w64),
+but no one documented the steps to do this. If you are doing this, please contribute them.
+
+Cross-compilation
+-------------------
+
+These steps can be performed on, for example, an Ubuntu VM. The depends system
+will also work on other Linux distributions, however the commands for
+installing the toolchain will be different.
+
+First install the toolchains:
+
+ sudo apt-get install g++-mingw-w64-i686 mingw-w64-i686-dev g++-mingw-w64-x86-64 mingw-w64-x86-64-dev
+
+To build executables for Windows 32-bit:
+
+ cd depends
+ make HOST=i686-w64-mingw32 -j4
+ cd ..
+ ./configure --prefix=`pwd`/depends/i686-w64-mingw32
+ make
+
+To build executables for Windows 64-bit:
+
+ cd depends
+ make HOST=x86_64-w64-mingw32 -j4
+ cd ..
+ ./configure --prefix=`pwd`/depends/x86_64-w64-mingw32
+ make
+
+For further documentation on the depends system see [README.md](../depends/README.md) in the depends directory.
