+### Turbo
+
+The [Turbo](doc/plugin/Turbo.md) plugin provides a way to send keystrokes in very quick succession while holding down a key.

 ### WinKeyToggle
 
 The [WinKeyToggle](doc/plugin/WinKeyToggle.md) plugin assists with toggling the Windows key on and off - a little something for those of us who game under Windows and are tired of accidentally popping up the start menu.

+# Kaleidoscope-Turbo
+
+The `Turbo` plugin provides an extra key one can place on their keymap. While the
+key is pressed or toggled, pressing other keys will generate quick repeated
+inputs independent of the OS key repeation mechanics.
+
+## Using the plugin
+
+To use the plugin, simply include the header and enable the plugin and place
+`Key_Turbo` somewhere on your keymap. You may add additionally configure
+specific behaviors of the plugin as shown:
+
+```c++
+#include <Kaleidoscope.h>
+#include <Kaleidoscope-Turbo.h>
+#include <Kaleidoscope-LEDControl.h>
+
+// somewhere in the keymap...
+Key_Turbo
+
+KALEIDOSCOPE_INIT_PLUGINS(LEDControl, Turbo);
+
+void setup() {
+    Kaleidoscope.setup();
+
+    Turbo.interval(30);
+    Turbo.toggle(true);
+    Turbo.flash(true);
+    Turbo.flashInterval(80);
+    Turbo.activeColor(CRGB(0x64, 0x96, 0xed));
+}
+```
+
+## Plugin properties
+
+The `Turbo` object has the following user-configurable properties:
+
+### `.interval([uint16_t])`
+
+> This property adjusts the timing between simulated keypresses. If you set this
+> too low, some programs might not like it. The default repeat rate for X11 is 25.
+>
+> Defaults to 10
+
+### `.flashInterval([uint16_t])`
+
+> This property adjusts the timing between the on/off states of the key LED.
+>
+> Defaults to 69
+
+### `.sticky([bool])`
+> This method makes the Turbo functionality sticky, so it remains in effect not only while
+>
+> it is held, but after it is released too, until it is toggled off with another tap. Without
+> arguments, the method enables the sticky functionality. Passing a boolean argument
+> sets stickiness to the given value.
+>
+> Defaults to `false`.
+
+### `.flash([bool])`
+
+> This property indicates whether the key should flash when enabled or remain a solid
+> color.
+>
+> Defaults to true.
+
+
+### `.activeColor([cRGB])`
+
+> This property indicates the color the key should become when enabled.
+>
+> Defaults to `CRGB(160, 0, 0)` (same as solidRed in default firmware).
