+When connecting to relays that support this NIP, clients SHOULD send an event of kind `20001`, meaning "client identification", with the content set to `"client identification for <relay hostname>"`.
 
 The relay MUST then use the event to verify the identity of the client and discard it afterwards. In the verification process the relay MUST check:
 
   1. if event signature is valid;
   2. if the content phrase matches the canonical phrase with the actual relay hostname in it;
-  3. if the event timestamp is not too far from the relay current timestamp.
+  3. if the event timestamp is not too far from the relay's current timestamp.
 
 If all is well, then the relay can use the identified pubkey to validate further requests for kind-4 events and only return kind-4 events that were either authored by the identified pubkey (`"pubkey": ...`) or are addressed to the identified pubkey (`"tags": ["p", ...]`).
