 This document standardizes the treatment given by clients of inline references of other events and profiles inside the `.content` of any event that has readable text in its `.content` (such as kinds 1 and 30023).
 
-When creating an event, clients should include mentions to other profiles and to other events in the middle of the `.content` using NIP-21 codes, such as `nostr:nprofile1qqsw3dy8cpu...6x2argwghx6egsqstvg`.
+When creating an event, clients should include mentions to other profiles and to other events in the middle of the `.content` using [NIP-21](21.md) codes, such as `nostr:nprofile1qqsw3dy8cpu...6x2argwghx6egsqstvg`.
 
 Including [NIP-10](10.md)-style tags (`["e", <hex-id>, <relay-url>, <marker>]`) for each reference is optional, clients should do it whenever they want the profile being mentioned to be notified of the mention, or when they want the referenced event to recognize their mention as a reply.
 
-A reader client that receives an event with such `nostr:...` mentions in its `.content` can do any desired context augmentation (for example, linking to the profile or showing a preview of the mentioned event contents) it wants in the process. If turning such mentions into links, they could become internal links, NIP-21 links or direct links to web clients that will handle these references.
