+include the corresponding locations.For example:
 
 .. code-block:: console
 
     C:\> \path\to\vcvarsall.bat x86_amd64
-    C:\> set LIB=C:\OpenSSL-1.0.1h-64bit\lib\VC\static;%LIB%

+    C:\> set INCLUDE=C:\OpenSSL\include;%INCLUDE%
+    C:\> pip install cryptography

+You can also choose to build statically or dynamically using the
+``PYCA_OPENSSL_INSTALL`` variable. Allowed values are ``static`` (default) and
+``dynamic``.
