-The plugin provides no methods or properties, the above is all it can do.
+You may also set optional parameters.

+
+##   Plugin methods
+
+The plugin provides the `BootGreetingEffect` object, with the following methods and
+properties:
+
+### `.search_key`
+
+> Set the key in the current keymap that should be activated with the pulsing
+> LED on startup.  The plugin will search from the top left to the bottom right
+> of the keyboard, row by row, to find this key.  The first matching key will
+> be selected.
+>
+> Defaults to `Key_LEDEffectNext`
+
+### `.key_row`
+
+> This is an optional override to explicitly set the selected key by exact row
+> and column.  This number is 0-indexed, so the top row is 0, the second row is
+> 1, etc.  Must set `.key_col` property for this feature to be enabled.
+
+### `.key_col`
+
+> This is an optional override to explicitly set the selected key by exact row
+> and column.  This number is 0-indexed, so the left-most column is 0, the 
+> second column is 1, etc.  Must set `.key_row` property for this feature to
+> be enabled.
+
+### `.timeout`
+
+> This property specifies the timeout (in milliseconds) for the effect to last.
+> When the keyboard is first connected, the pulsing LED effect will last for
+> this duration before turning off.
+>
+> Defaults to `9200` ms.
+
+### `.hue`
+
+> This property sets the color hue that the LED pulsing effect.
+>
+> The default is `170`, which is a blue color.
