+To use the library you will need one of the compatible boards:
+- [Arduino® UNO R4 WiFi](https://docs.arduino.cc/hardware/uno-r4-wifi)
+- [Arduino® UNO R4 Minima](https://store.arduino.cc/products/uno-r4-minima)

 ## How Capacitive Sensing Works
 
 Imagine the sensor as creating an invisible electric field around itself. When a conductive object (like your finger) approaches, it's like dropping a stone into a calm pond - the field gets disturbed. The sensor detects this disturbance as a change in capacitance, which is essentially how much electrical charge the system can store.

+### Circuit
 
 Here's a simple example to get you started with capacitive sensing on the UNO R4. For this example, we are connecting a single piece of any conductive material to the pin `D0` on the Board.
