+On MSVC it's unfortunately not always a trivial process acquiring OpenSSL. A couple of possibilities
+are downloading precompiled binaries for OpenSSL 1.1.0, or installing OpenSSL 1.0.2 using vcpkg.

+#### Installing OpenSSL 1.1.0 using precompiiled binaries

 Perhaps the easiest way to do this right now is to download [precompiled
 binaries] and install them on your system. Currently it's recommended to
 install the 1.1.0 (non-light) installation if you're choosing this route.

+#### Installing OpenSSL 1.0.2 using vcpkg
+
+Install [vcpkg](https://github.com/Microsoft/vcpkg), and install the OpenSSL port like this:
+
+```Batchfile
+vcpkg install openssl:x64-windows
+set VCPKG_ROOT=c:\path\to\vcpkg\installation
+cargo build

+#### Acquiring Root Certificates
+
+Neither of the above OpenSSL distributions ship with any root certificates.
 So to make requests to servers on the internet, you have to install them
 manually. Download the [cacert.pem file from here], copy it somewhere safe
 (`C:\OpenSSL-Win64\certs` is a good place) and point the `SSL_CERT_FILE`
