+This FCEUX Lua script provides an enhanced HUD for R.C. Pro-Am.
 
 Screenshot
 ==========
 ![R.C. Pro-Am Enhanced HUD](./screenshot.png)
 
 Explanation
 ===========
-asdfghjkl
+The HUD replaces a number of items with more detailed counterparts.
+
+Lap Counter
+-----------
+The lap counter has been expanded to show what lap each car is on.
+`#L` represents the number of laps in the race.
+
+Level Display
+-------------
+The level display now includes the base track design. `LV:##` is the level
+number as displayed by the game, and `T:#` is the actual track design.
+
+Orange Car Danger Alert
+-----------------------
+One thing to watch out for in R.C. Pro-Am is the orange car. If you manage to
+destroy 10 cars with weapons, the orange car will go extremely fast.
+
+The counter just below the race screen lets you know how many cars have been
+killed (`DANGER: ##`) or if the orange car is angry (`ORANGE CAR MAD`).
+
+Speed
+-----
+The speedometer now shows the current and maximum speeds for each car.
+
+To-Do
+=====
+* Show the number of continues on the continue screen
+* Other things???
