Hi,  
I still know your docu site [https://dietpi.com/docs/](https://dietpi.com/docs/).

I miss some background informations about DietPi.

It is “Debian-based”. Which version/branch do you use?

Which repos does a DietPi installation use? What is the content of the sources file?

Hi,

DietPi is not an own OS, DietPi is a set of scripts on top of a Debian base image. Depending on SBC, DietPi is using different base images like plain Debian, Maveric, Armbian or in case of Raspberry Pi - Raspberry OS. DietPi is using standard Debian repositories as they are provided by the base image.
