Yep, it is downloaded, same with LND and etc. The thing I am confused in how to do is the following info: 
    
1. Ensure your computer or phone is running Tor: https://docs.start9.com/latest/guides/device-guides/ (THIS LINK IS NOT WORKING)

2. In Nostr Properties, copy your Nostr Relay Websocket URL (e.g. ws://<address>.onion), and paste it into your Nostr client relay list.

*Note: there is also a Local (e.g. wss://<address>.local) URL is included in Properties. We do not recommend using this interface except to sanity check that your relay working in certain cases. No one will be able to access your .local URL except you and anyone else connected to the same LAN.
