How to read the value of a photoresistor and print it out in serial monitor

[babynisse]

@Idahowalker

void setup()
{
  pinMode(12, OUTPUT);
  //pinMode(A0, INPUT);
  Serial.begin(9600);
}

void loop()
{
  int aoRead = analogRead(A0);
  
  if (aoRead > 1024/2 )
  {
    Serial.println("av");
    delay(5000);
  }
  if ( aoRead <= 1024/2)
  {
    Serial.println("Avlest lysmengde er: ");//print out lightlevel value
    digitalWrite(12, HIGH);
    delay(1000); // Wait for 1000 millisecond(s)
    digitalWrite(12, LOW);
    delay(1000); // Wait for 1000 millisecond(s)
  }
}

I want to know how much light detection it is on the photoresist and print it out in serialmonitor.
