-Here's how to install Scapy on Mac OS 10.4 (Tiger) or 10.5 (Leopard).
+On Mac OS X, Scapy does not work natively. You need to install Python bindings
+to use libdnet and libpcap. You can choose to install using either Homebrew or
+MacPorts. They both work fine, yet Homebrew is used to run unit tests with
+`Travis CI <https://travis-ci.org>`_.
