Serial Monitor to LCD

Hey guys, still very new to Arduino. Could someone point me in the direction I need to go to learn how to send strings from the serial monitor to my LCD?

I have the LCD connected and I can display strings with lcd.print('Hello World'); but i'm not sure how to send them to be displayed from the serial monitor.

Thanks for any help you have :)

Something like this would do it:

void setup() (Serial.begin(9600);}
void loop() {
    if (Serial.available())
