 # RGB Matrix Lighting
 
+This feature allows you to use RGB LED matrices driven by external drivers. It hooks into the RGBLIGHT system so you can use the same keycodes as RGBLIGHT to control it.
+
+If you want to use single color LED's you should use the [LED Matrix Subsystem](feature_led_matrix.md) instead.

 The format for the matrix position used in this array is `{row | (col << 4)}`. The `x` is between (inclusive) 0-224, and `y` is between (inclusive) 0-64. The easiest way to calculate these positions is:
 
-    x = 224 / ( NUMBER_OF_ROWS - 1 ) * ROW_POSITION
-    y = 64 / (NUMBER_OF_COLS - 1 ) * COL_POSITION
+    x = 224 / ( NUMBER_OF_COLS - 1 ) * ROW_POSITION
+    y = 64 / (NUMBER_OF_ROWS - 1 ) * COL_POSITION
 
 Where all variables are decimels/floats.
