 ## Usage
 
+We expect that clients will hit specific endpoints for creation and updates (POST) and deletion (DELETE). 
+
+Although the NIP accepts dots and underscores in names, we only allow a smaller subset without them so that we are more friendly to http redirection.
+
 ### POST Endpoint
 
 To securely authenticate POST requests to the `nip05api` endpoint, utilize the [NIP-98](https://github.com/nostr-protocol/nips/blob/master/98.md) HTTP authentication method. This involves creating a signed Nostr event as per NIP 98 specifications, encoding it in base64, and including it in the `Authorization` header.

+### External Setup
+
+We configure rate limits and redirects to njump through our [Traefik infra config](https://github.com/planetary-social/ansible-scripts/tree/main/roles/nos_social)
