 This is an experimental keymap adding support for RGB Matrix on the K-Type.
 
-The keyboard should now support full RGB lightings. The lighting animations are running at 10 fps for performance reasons.
-You can configure this by changing the `RGB_MATRIX_LED_FLUSH_LIMIT` inside the `config.h` file to a lower value.
-For example `RGB_MATRIX_LED_FLUSH_LIMIT 16` would mean that the animations run every 16 ms or at 60 fps.
+The board has two IS31FL3733 LED controllers, but they are each on different I2C buses, which QMK's `i2c_master` implementation currently does not support. As a result, all the keys after the left shift will not be lit.
