A simple watchdog for Digispark (Attiny85)

Hi! I’ve found some documentation about it, but with lot of complicated staff that I don’t need. I’m just looking for something simple, like this:

#include <avr/wdt.h>

void setup () {

void loop () {

I see 2 problems, wdt_reset(); doesn’t extend the watchdog, 2 seconds after the bootloader ends the controller stops. It stops (P1 output was high and became low) and doesn’t reboot.
