 ### 1. Setup Secrets
 1.  `cp secrets/secrets.nix.example secrets/secrets.nix`
 2.  Fill in the values (generate random keys, etc).
+    - `openssl rand -base64 32` is a good way to make a new key
     - `tailscaleKey` must be a **Reusable** key from the Tailscale admin console.
 
 ### 2. Verify Configuration Locally
