Where Debian fits
Choose it when a defined release and a conservative maintenance workflow suit the machine.
Check before you choose
Check firmware needs and the release support policy before installing on unfamiliar hardware.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
A desktop distribution, a server system and a specialist toolkit serve different purposes. Decide whether you want a fixed release, rolling updates or a declarative setup before comparing desktop appearances.
