 This library is intended to interact with button pluged on a ESP8266 using the Arduino SDK
 
 Code Example
-```Arduino
+```c++
 #include <HIB.h>
 
-HIB *button ;
-HIB *button2 ;
+HIB *button;
+HIB *button2;
 
-void onButtonPressed(uint8_t pin){
-  Serial.printf("Sketch on button %d pressed \n", pin);
-  }
+void onButtonPressed(uint8_t pin) { Serial.printf("Button %d pressed \n", pin); }
 
-void setup() {
+void setup()
+{
 	Serial.begin(115200);
 	// put your setup code here, to run once:
 	button  = new HIB(0, HIGH, onButtonPressed);
 	button2 = new HIB(4, HIGH, onButtonPressed);
