+# SERVER/CLIENT
+    When in server or client mode, the game can be played across a network. If desired, a player could design an AI to act as a client instead of using the client mode and intermediary filesystem.
+
+## Protocol
+    The server is accesible on port 11715
+
+    To perform the handshake the server will write to the socket with the format "player PLAYER_ID name GAME_NAME", it will expect this exact information to be written back to in reply.
+
+    Once handshake is performed, the server will write to the socket in the form of the Gamestate file as above.
+
+    The server will then wait for a new-line delimited and END terminated list of orders
+
+    This will be repeated until the game is over
