 You should replace the version string on the first line as appropriate for your
 build.
 
+Using your own OpenSSL on OS X
+------------------------------
+
+To link cryptography against a custom version of OpenSSL you'll need to set
+``ARCHFLAGS``, ``LDFLAGS``, and ``CFLAGS``. OpenSSL can be installed via
+`Homebrew`_::
+
+    brew install openssl
+
+Then install cryptography linking against the brewed version::
+
+    env ARCHFLAGS="-arch x86_64" LDFLAGS="-L/usr/local/opt/openssl/lib" CFLAGS="-I/usr/local/opt/openssl/include" pip install cryptography
+
