-# Targets
-### ttrts
-Main TTRTS binary, runs from the command line and acts as host for games
+# NAME
+	ttrts - Tiny Terminal RTS
 
-### test (ttrts-test)
-Test binary, to be compiled and run to test various functionality
+# SYNOPSIS
+	ttrts [--server] [--client] [--host=HOSTNAME] [--map=MAPFILE]
  
-### gen (ttrts-gen)
-Binary to generate example map files
+# DESCRIPTION
+	ttrts is a tiny terminal based RTS that uses text files as order lists to control the units
 
-# Libraries
-### game
-Implementation of the RTS rules and simulation
+	This means that any user, program or cat that can read and write to text files can play the game
 
-### maths
-Simple maths library for 2D calculations and types
+# RETURN VALUE
+    ttrts will return -1 on error, or the winning player on completion
 
-### scripts
-Directory of scripts used in build process
+# OPTIONS
+    --server - Run in server mode, must provide a map file
+
+    --client - Run in client mode, must provide a hostname for a running server
+
+	--map=MAPFILE - File to read in the initial game state. Local or in ${TTRTS_MAPS}
+
+    --host=HOSTNAME - Name of host to connect to in client mode
+
+# USAGE
+	When invoked, ttrts will set up the game in a directory within ${TTRTS_GAMES} by the name of the map
+
+	The files in this directory can be read and interpreted by human, robot or cat
+
+	ttrts will then await order files from each participant
+
+	Once all order files have been received ttrts will calculate the turn and output a new gamestate file
+
+    In server and client mode, the client will output and read in these files while the server simulates the game
+
+	This process repeats until the game is over
+
+# ENVIRONMENT
+	${TTRTS_MAPS}  - Map file lookup location, defaults to `/usr/share/ttrts/maps/`
+
+	${TTRTS_GAMES} - Game directory for I/O, defaults to `/tmp/`

+
+-----------------------------------------------------------
+# 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
+
+-----------------------------------------------------------
+# GAMEPLAY
+
+	The game takes place in a series of simultaneous turns on an arbitrarily sized 2D board
+
+	Each turn, the client outputs a gamestate file and waits for an order file from each player
+
+	All commands are evaluated simultaneously with friendly fire enabled by default
+
+	The game is over when any of three conditions are met -
+    * All remaining units are controlled by a single player
+    * No units are left (draw)
+    * All units left are unable to move (draw)
+
+# UNITS
+	Each unit occupies a single tile on the board, facing in a compass direction (NESW)
+
+	Units will only accept orders from their owner
+
+	Units can receive only a single order each turn
+
+	Units cannot occupy the same tile as other units/walls
+
+# ORDERS
+### F   - Move unit [F]orward one space, leaving a wall
+
+	This wall will remain until the end of the game, blocking movement to that tile
+
+	Movement orders have no effect if impossible, eg.
+    * Attempting to move outside of map
+    * Attempting to move on to tile occupied by unit/wall
+
+### L/R - Rotate unit [L]eft or [R]ight
+
+	Unit will rotate clockwise or counter-clockwise, this order cannot fail
+
+### A   - [A]ttack in straight line in front of unit
+
+	Attack will continue forward until unit can't progress, all units within the path of the attack are destroyed.

-# ttrts - Tiny Terminal RTS v0.3.0
-
-## SYNOPSIS
-	ttrts MAPFILE
-
-## DESCRIPTION
-	ttrts is a tiny terminal based RTS where that uses text
-	files as order lists to control it's units
-
-	This means that any user, program or cat that can read
-	and write to text files can play the game
-
-## OPTIONS
-	MAPFILE - File to read in the initial game state from
-
-## USAGE
-	When invoked, ttrts will set up the game in a local 
-	directory called `ttrts_{GAME_NAME}`
-
-	The GAMESTATE files in this directory can be read and
-	interpreted by human, robot or cat. 
-
-	ttrts will then await ORDER files from each participant
-
-	Once all ORDER files have been received ttrts will 
-	calculate the turn and output a new GAMESTATE file
-
-	This process repeats until the game is over
-
------------------------------------------------------------
-# TTRTS GAMEPLAY
-
-## RULES
-	The game takes place in a series of simultaneous turns
-	on an arbitrarily sized 2D board
-
-	Each turn, the client outputs a GAMESTATE file and 
-	waits for an ORDER file from each player
-
-	All commands are evaluated simultaneously with friendly
-	fire enabled by default
-
-	The game is over when any of three conditions are met -
-	* All remaining units are controlled by a single player
-	* No units are left (draw)
-	* All units left are unable to move (draw)
-
-## UNITS
-	Each unit occupies a single tile on the board, facing 
-	in a compass direction (NESW)
-
-	Units will only accept orders from their owner
-
-	Units can receive only a single order each turn
-
-	Units cannot occupy the same tile as other units/walls
-
-## ORDERS
-	F   - Move unit [F]orward one space, leaving a wall
-	     
-	This wall will remain until the end of the game, 
-	blocking movement to that tile
-
-	Movement orders have no effect if impossible, eg.
-	* Attempting to move outside of map
-	* Attempting to move on to tile occupied by unit/wall
-
-	L/R - Rotate unit [L]eft or [R]ight
-
-	Unit will rotate clockwise or counter-clockwise,
-	this order cannot fail
-
-	A   - [A]ttack in straight line in front of unit
-	      
-	Attack will continue forward until unit can't progress,
-	all units within the path of the attack are destroyed.
-
