-Install OpenSSL from [here][1]. Cargo will not be able to find OpenSSL if it's
+On Windows, consider building with [mingw-w64](http://mingw-w64.org/).
+Build script will try to find mingw in `PATH` environment variable to provide
+Cargo with location where openssl libs from mingw-w64 package may be found.
+If you followed guide [Building on Windows](https://github.com/rust-lang/rust#building-on-windows)
+from rust repo, then you should have [MSYS2](http://msys2.github.io/) with
+`mingw-w64-openssl` installed as part of `mingw-w64-x86_64-toolchain`
+(or `mingw-w64-i686-toolchain`) package.
+
+Alternatively, install OpenSSL from [here][1]. Cargo will not be able to find OpenSSL if it's
 installed to the default location. You can either copy the `include/openssl`
 directory, `libssl32.dll`, and `libeay32.dll` to locations that Cargo can find
 or pass the location to Cargo via environment variables:
