how to add a new python script daemon

[klankschap]

i'm new to arch linux.
i'm running archlinux on a rasp.
i'd like to autostart at boot time a python script which will draw on the screen using pygame.
in kiosk mode, without user interaction.
can some tell me how to setup such daemon?
i did place the script in /usr/sbin and it can be launched.
How to add.
In debian there is the /etc/init.d/skeleton which does the job.
How is it done in arch linux ?

Thanks

yes, that is the area to dig into, but it is unclear as how to make it work.

What are the steps needed to get the app running in kiosk mode?
