+There is basic support for addressable LED matrix lighting with a selection of I2C ISSI Lumissil LED controllers through a shared common driver. To enable it, add this to your `rules.mk`:
+
+```makefile
+LED_MATRIX_ENABLE = yes
+LED_MATRIX_DRIVER = <driver name>
+```
+
+Where `<driver name>` is the applicable LED driver chip as below
+
+| Driver Name | Data Sheet | Capability |
+|-------------|------------|------------|

+
+You can use between 1 and 4 IC's. Do not specify `DRIVER_ADDR_<N>` define for IC's if not present on your keyboard. The `DRIVER_ADDR_1` default assumes that all Address pins on the controller have been connected to GND. Drivers that have SYNC functionality have the default settings to disable if 1 driver. If more than 1 drivers then `DRIVER_ADDR_1` will be set to Master and the remaiing ones set to Slave.
+
+Configure the hardware via your `config.h`:
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `ISSI_TIMEOUT` | (Optional) How long to wait for i2c messages, in milliseconds | 100 |
+| `ISSI_PERSISTENCE` | (Optional) Retry failed messages this many times | 0 |
+| `DRIVER_COUNT` | (Required) How many LED driver IC's are present | |
+| `DRIVER_LED_TOTAL` | (Required) How many LED lights are present across all drivers | |

+#define DRIVER_1_LED_TOTAL 66
+#define DRIVER_2_LED_TOTAL 42
+#define DRIVER_LED_TOTAL (DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL)
+```
+!> Note the parentheses, this is so when `DRIVER_LED_TOTAL` is used in code and expanded, the values are added together before any additional math is applied to them. As an example, `rand() % (DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL)` will give very different results than `rand() % DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL`.
+
+Currently only 4 drivers are supported, but it would be trivial to support for more. Note that using a combination of different drivers is not supported. All drivers must be of the same model.
+
+Define these arrays listing all the LEDs in your `<keyboard>.c`:
+
+```c

+ * | LED address

+```
+
+Where `CSx_SWx` is the location of the LED in the matrix defined by the datasheet. The `driver` is the index of the driver you defined in your `config.h` (`0`, `1`, `2`, or `3` for now).
+
+`ISSI_MANUAL_SCALING` is used to override the Scaling for individual LED's. By default they will be set as per `ISSI_SCAL_LED`. In `config.h` set how many LED's you want to manually set scaling for.
+Eg `#define ISSI_MANUAL_SCALING 3`
+
+Then Define the array listing all the LEDs you want to override in your `<keyboard>.c`:
+
+```c
+const is31_led __flash g_is31_scaling[ISSI_MANUAL_SCALING] = {
+ * LED Index
+ * | Scaling
+ * | | */
+ {5, 120},
+ {9, 120},
+ ....
+}
+```
+
+Where LED Index is the position of the LED in the `g_is31_leds` array. The `scaling` value between 0 and 255 to be written to the Scaling Register.
