# Convert Armbian to DietPi - Lightweight Debian OS for SBC

NOTE: The DietPi script only works on Debian builds of Armbian. Running it on Ubuntu based builds will exit with an unsupported distribution error. It is recommended to perform this process on a fresh installation of Armbian.

## What is DietPi?

DietPi is extremely lightweight at its core, with features of low process/memory footprint and DietPi-RAMlog installed by default, to get the maximum performance from your device. -https://dietpi.com/
