+# Led Selection
+
+The <span style="color: #00ff00;">Color Select</span>, <span style="color: #3366ff;">Pattern Select</span>, and <span style="color: #ffffff;">Randomizer</span> will change only the leds which were selected upon entering the menu.
+
+## How It Works
+
+The Randomizer uses intelligent algorithms based on color theory to create visually appealing and unique modes. This allows creation of coherent colorsets with an added element of randomization.
+
+## Random Seed
+The Randomizer chooses a starting point based on the mode you start from. This means that starting with the same mode will produce the same sequence of random results.
+
+For those familiar, the randomizer seed is a checksum of the current mode.
+
+## Using the Randomizer
+
+1. **Pick a Mode to Randomize**: Navigate to the mode you want to randomize and hold the button until the leds flash white
+2. **Enter the Randomizer**: Long click to enter the white menu
+3. **Pick the Leds to Randomize**: Short click to cycle through led groups, long click to select a group
+4. **Generate a New Mode**: Short click to randomize as many times as you like
+5. **Save and Exit**: Long click to save the mode and exit.
+
+## Auto Randomization
+
+While cycling through random modes in the randomizer menu, perform three consecutive short clicks to enable _Auto Cycle_ and automatically generate a new mode every few seconds. Short click to stop cycling.
+
+## Advanced Randomization
+
+See [Advanced Menus](advanced_menus.html) to enable this feature.
+
+With the _advanced randomizer_, after selecting the led group to randomize, you may choose:
+
+ - **Rainbow Ribbon**: Randomize Colorset only  
+ - **White Strobe**: Randomize Pattern only  
+ - **Rainbow Strobe**: Randomize both pattern & colorset  
+
+Other than this extra option the _advanced randomizer_ will behave the exact same as the basic randomizer.
