Once Pi Relay is running, you don't have to do anything! Since you have an e-paper display, you can check in on its activity to see how much bandwidth you've donated.
One of the tricky things about operating a relay is keeping it up-to-date. We handle this for you by automatically updating your device. You'll be able to see the Tor version on the diaplay to confirm it's working.
At first, you'll notice "No flags yet." After it's running for some time flags like "Running," "Valid," "Stable," or "Fast" will begin to display.
You'll see a bar chart visualizing your bandwidth contributions relative to your monthly quota. Your display refreshes every minute, so you always know your most recent activity.
