     $ pip install cryptography
 
 If you prefer to compile it yourself you'll need to have OpenSSL installed.
-There are `pre-compiled binaries`_ available. If your installation is in an
-unusual location set the ``LIB`` and ``INCLUDE`` environment variables to
-include the corresponding locations.For example:
+You can compile OpenSSL yourself as well or use the binaries we build for our
+release infrastructure (`32-bit`_ and `64-bit`_). Wherever you place your copy
+of OpenSSL you'll need to set the ``LIB`` and ``INCLUDE`` environment variables
+to include the proper locations. For example:
 
 .. code-block:: console
 
     C:\> \path\to\vcvarsall.bat x86_amd64
-    C:\> set LIB=C:\OpenSSL\lib\VC\static;C:\OpenSSL\lib;%LIB%
-    C:\> set INCLUDE=C:\OpenSSL\include;%INCLUDE%
+    C:\> set LIB=C:\OpenSSL-win64\lib;%LIB%
+    C:\> set INCLUDE=C:\OpenSSL-win64\include;%INCLUDE%
     C:\> pip install cryptography
 
-You can also choose to build statically or dynamically using the
-``PYCA_WINDOWS_LINK_TYPE`` variable. Allowed values are ``static`` (default)
-and ``dynamic``.

-    C:\> \path\to\vcvarsall.bat x86_amd64
