 PyBitmessage
-============
+============
+
+Bitmessage is a P2P communications protocol used to send encrypted messages to
+another person or to many subscribers. It is decentralized and trustless,
+meaning that you need-not inherently trust any entities like root certificate
+authorities. It uses strong authentication which means that the sender of a
+message cannot be spoofed, and it aims to hide "non-content" data, like the
+sender and receiver of messages, from passive eavesdroppers like those running
+warrantless wiretapping programs.
