How to autostart gpt_dog.py on power-on of PiDog?

I want to autostart gpt_dog.py on power-on of PiDog. Is there any tutorial to teach it ?

It is not recommended to use gpt_dog.py for automatic startup. If you set it to run automatically at boot, other examples may not function properly.

Thank you for your reply. I understand your point that the other examples will be affected. Please close this question. Thank you.
