+twister is an experimental decentralized P2P microblogging platform leveraging
+from the free software implementations of Bitcoin and BitTorrent protocols.
+
+User registration and authentication is provided by a bitcoin-like network, so
+it is completely distributed (does not depend on any central authority).
+
+Post distribution uses kademlia DHT network and bittorrent-like swarms, both are
+provided by libtorrent.
+
+Both Bitcoin and libtorrent versions included here are highly patched and do not
+interoperate with existing networks (on purpose).
+
+Warning!  This is alpha software! In other words: this software is probably
+difficult to compile, it is not feature-complete, it can be unstable, and it may
+crash causing data loss. You have been warned.
+
+If you choose to continue you probably must fall into one of the following
+categories:
+
+    You are a developer.
+    You are an early adopter (who wants to reserve your nickname).
+    You are a masochist.
