# Matrix Initialization Code
-Before a keyboard can be used the hardware must be initialized. QMK handles initialization of the keyboard matrix itself, but if you have other hardware like LED's or i²c controllers you will need to set up that hardware before it can be used.

### Example `matrix_init_user()` Implementation
You should use this function if you need custom matrix scanning code. It can also be used for custom status output (such as LED's or a display) or other functionality that you want to trigger regularly even when the user isn't typing.
+# Keyboard Idling/Wake Code
+
+If the board supports it, it can be "idled", by stopping a number of functions. A good example of this is RGB lights or backlights. This can save on power consumption, or may be better behavior for your keyboard.
+
+This is controlled by two functions: `suspend_power_down_*` and `suspend_wakeup_init_*`, which are called when the system is board is idled and when it wakes up, respectively.
+
+
+### Example suspend_power_down_user() and suspend_wakeup_init_user() Implementation
+
+This example, at the keyboard level, sets up B1, B2, and B3 as LED pins.
+
+```
+void suspend_power_down_user(void)
+{
+ rgb_matrix_set_suspend_state(true);
+}
+
+void suspend_wakeup_init_user(void)
+{
+ rgb_matrix_set_suspend_state(false);
+}
+
+```

# Layer Change Code
-Thir runs code every time that the layers get changed. This can be useful for layer indication, or custom layer handling.
