+    Windows and OpenSSL: How do I install and build with OpenSSL on Microsoft Windows?
+][
+    An easy method is to use command-line package installers chocolatey or scoop. Examples:
+    "choco install -y openssl --x86 --version 1.1.1.700" or 
+    "scoop install openssl@1.1.1g -a 32bit -g"
+
+    If you've installed OpenSSL to a directory with spaces in the name, it's often
+    preferable to create a symbolic link so that you may use a simpler path, such as:
+
+    mklink /D "OpenSSL" "Program Files (x86)\\OpenSSL-Win32"
 
+    Set the environment variable OPENSSL_ROOT to the location of the new install:
+
+    set OPENSSL_ROOT=C:/OpenSSL
+
+    Then, proceed to build. Refer to beast/.dockers/windows-vs-32/Dockerfile for an example of building the test cases with OpenSSL.
