Need Simple Served Web Page Control

On the contrary, it is complete since it does not need a setup() and loop()
Just try building the sample as is.

I've also posted a way to reuse the SoftAP function to interact with the devices

If you then add

void setup() {
  WiFi.listen();
}

The device will start in SoftAP Mode and you can interact with it right away on 192.168.0.1/<whateverYourPage.html>/
