-## Usage  
+## Demo Code Explanation  
 
-- Power the device using the rechargeable battery.  
-- Use the buttons for input.  
-- Visual feedback is displayed on the OLED screen.  
-- Audio feedback is provided through the piezo buzzer.  
+The provided demo code demonstrates the main features of the SmartCube, focusing on system initialization, button handling, OLED display output, and WiFi management. Below is a breakdown of its components:
+
+### Key Features  
+
+1. **WiFi Management**:  
+   - The `cubeWifiManager` class manages WiFi connectivity seamlessly.  
+   - If no known WiFi network is available, it starts a configuration portal and creates an access point (AP), allowing users to connect the SmartCube to a network from another WiFi-enabled device.  
+   - The OLED display shows the access point details, such as the AP name and IP address, making the setup process user-friendly and accessible.
+
+2. **Button Handling**:  
+   - Buttons are mapped to specific GPIO pins: `PIN_BTN_L` (Left), `PIN_BTN_M` (Middle), and `PIN_BTN_R` (Right).  
+   - The `cubeButtonHandler()` function, executed in the `loop()`, monitors and interprets button presses, differentiating between short and long presses.  
+
+#### Default Button Actions  
+- **Right Button**:  
+  - *Short Press*: Turns the OLED display **on** (if previously off).  
+  - *Long Press*: Turns the OLED display **off**, helping conserve power.  
+
+- **Left + Middle Buttons (Simultaneous Long Press)**:  
+  - Triggers an ESP8266 reboot, effectively restarting the device.
