1. Get old laptop 2. Install Umbrel 3. Install Nostr Relay app 4. Add relay to Nostr Client
Here's how to add Umbrel Nostr Relay: https://apps.umbrel.com/app/nostr-relay
I have a node that I built with umbrel. I recently downloaded Nostr relay. Not sure what else to do. I’ll spend a bit more time looking at it.
