+## Two Player Mode ##
+
+The ANSI mode mentioned above was cloned to create a two-player mode with the
+same terminal-compatible ANSI-color UI. Both players must reside on the same
+computer and have permission to create FIFOs under `/tmp/` with `mknod()`.
+
+The first player to launch Go plays as black and the second player to launch
+plays as white.
+
+All communication in the client is strictly synchronous. Thus, commands to save
+or analyze the game may only occur during your turn. Outside your turn, your
+client will only display the following message, accepting no other input until
+a move is received from your opponent.
+
+    Waiting to receive move from other player...
+
+When a game terminates, each player is provided an opportunity to save an SGF
+file for later analysis. Continuing a multiplayer game from SGF is not
+currently supported.
