+How to Play Air Traffic Controller - Single Player mode:
+========================================================
+
+When you start a single player game, you are presented with a decent amount
+of information. It is your job, as an air traffic controller, to read it and
+respond to it as necessary.
+
+To tell a pilot to do something, you have to issue a command. All commands
+have the same basic syntax:
+
+	AIRCRAFT ID: COMMAND params...
+
+At this time, the only aircraft ID supported is the flight number.
+
+NOTE: Unfortunately, the command enterting facility is very rudimentary and
+you must follow the syntax closely, or risk crashing the game.
+
+The following commands are supported:
+
+1) ALT		=> Change altitude
+
+	This command has one parameter: the altitude the aircraft should
+	climb/decent to.
+
+2) HEAD		=> Change heading
+
+	This command has one parameter: the new heading.
+	
+	NOTE: This command WILL change in future to allow turning right or
+	left to specified heading.
+
+3) SQUAWK	=> Change squawk code
+
+	This command has one parameter: the new squawk code, a 4 digit octal
+	number (digits 0-7 only)
+
+Here's a little example...Say there is an aircraft (Delta 79) that has
+heading 270 at 4000, and we want it to decend to 2500 and turn to heading 220.
+The two commands we would issue are:
+
+DELTA 79: ALT 2500
+DELTA 79: HEAD 220
+
+For ease of use, pressing either ';' or ':' will produce ': '.
+
+NOTE: It is imperative that you include exactly one space between the "DELTA" and "79", ":" and "HEAD"/"ALT", and "HEAD"/"ALT" and "2500"/"220".
