Hi @🦖  I'm an extremely newbie and I don't know how to publish preferred relays. About the configuration, I installed the latest version.. 
Yes I've to learn so much  

 just add these relays on your client:
wss://relay.damus.io
wss://relay.snort.social
wss://nos.lol
wsd://relay.mostr.pub 

 *wss:// 

 I've done it. Thanks
