+The most basic form of using CUE.NET is by individually setting the color of every LED and manually triggering an update.  
+_Even if this seems easy to use it's not recommended. You should take a look at [groups](https://github.com/DarthAffe/CUE.NET/wiki/Understanding-CUE.NET-keygroups-%28keyboard-only%29) and [brushes](https://github.com/DarthAffe/CUE.NET/wiki/Understanding-CUE.NET-brushes) instead._  
+
+Since a keyboard consists of keys which contains a LED and mouse-/headset-devices only contains LEDs the usage differs slightly.
+
+#### Keyboard ####
+This code would set the color of the A-key to red and the color of the B-key to green. All other keys would keep the color they had before:
+```C#
+CorsairKeyboard keyboard = CueSDK.KeyboardSDK;
+keyboard['A'].Led.Color = Color.Red;
+keyboard[CorsairKeyboardKeyId.B].Led.Color = Color.Green;
+keyboard.Update();
+```
+
+#### Mouse/Headset ####
+This code would set the color of the B1-LED (location depends on the device) to blue. All other LEDs would keep the color they had before:
+```C#
+CorsairMouse mouse = CueSDK.MouseSDK;
+mouse[CorsairMouseLedId.B1].Color = Color.Blue;
+mouse.Update();
+```
+
+### Manual/automatic update ###
+By default you need to call _device_.Update() every time you want your changes be written to the device. Since this is quite unhandy in some situations you can activate automatic updates for each device by calling:
+```C#
+CorsairKeyboard keyboard = CueSDK.KeyboardSDK;
+keyboard.UpdateMode = UpdateMode.Continuous;
+```
+This would instruct the keyboard to apply changes 30 times a second (every 33.3 millisecond) [default value].
+
+Of course you can change the update rate to better fit your needs. (Be aware of the performance impact of high update-rates!)
+The value is set in seconds. You can calculate it quite easy by dividing 1 by the amount of updates per second you need. The following example would set the update-rate to 60 times a second:
+```C#
+CorsairKeyboard keyboard = CueSDK.KeyboardSDK;
+keyboard.UpdateFrequency = 1f/60f;
+```
