+# 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.
