If your client does not use Outbox model yet, please go to https://metadata.nostr.com/, click relays and set it up. 

Without that setting, Outbox clients cannot find your posts. Your follows won't find you. 

Tips: 
- You only need a maximum of 4 relays in that list. 
- Mark as "Write" the relays that have all content written and signed by you.
- Mark as "Read" the public relays that you want your follows to use when sending notifications to you.

That's all you need to do.
