Raspberry Pi (Pi 4 / Pi 5)
One image boots both the Raspberry Pi 4 and the Pi 5 — the same file, no separate downloads. It carries the operating system, the app, and two update slots so the first update has somewhere to go.
1. Get the image
Section titled “1. Get the image”Download the latest beta image:
You do not need to decompress it — Raspberry Pi Imager flashes .img.xz directly.
2. Flash it
Section titled “2. Flash it”Use Raspberry Pi Imager (or Balena Etcher). Detailed, screen-by-screen walkthroughs:
In Imager: Choose OS → Use custom → pick the .img.xz, Choose Storage → your card, Write.
3. Boot the Pi
Section titled “3. Boot the Pi”Insert the card, connect Ethernet (or set up Wi-Fi on first boot), and power on. The first boot expands storage and starts the services; give it 2–3 minutes.
4. Open it in a browser
Section titled “4. Open it in a browser”On a computer on the same network, go to:

Then continue to First boot.
Which Pi?
Section titled “Which Pi?”Either works. A Pi 5 is noticeably snappier for the web console and for drivers that build native bits (e.g. the Apple TV sidecar). A Pi 4 (4 GB+) is perfectly capable for most setups.
