 ### Building on Windows
 
+There are two prominent ABIs in use on Windows: the native (MSVC) ABI used by
+Visual Studio, and the GNU ABI used by the GCC toolchain. Which version of Rust
+you need depends largely on what C/C++ libraries you want to interoperate with:
+for interop with software produced by Visual Studio use the MSVC build of Rust;
+for interop with GNU software built using the MinGW/MSYS2 toolchain use the GNU
+build.
+
+
+#### MinGW

 [MSYS2](http://msys2.github.io/) can be used to easily build Rust on Windows:

+#### MSVC
+
+MSVC builds of Rust additionally require an installation of Visual Studio 2013
+(or later) so `rustc` can use its linker. Make sure to check the “C++ tools”
+option. In addition, `cmake` needs to be installed to build LLVM.
+
+With these dependencies installed, the build takes two steps:
