-Account delegation via kind-0
+Persona
 -------------------
 
 `draft` `optional`
 
-Defines how to use kind-0 for account delegation.
-The clients responsible for account management create and post the delegator kind-0 event.
-A user can utilize the delegatee account listed in their own delegator event. If a user creates a delegatee kind-0 event and it is valid, it is considered to represent the same identity with a different key pair.
+This NIP defines how to create personae for a user. A persona represents an account owned by the main account but serving a distinct purpose. It is not intended to function as a master-subkey system or a form of delegation. The relationship between the main account and the persona account is expressed using `kind 0` events with a few tags.
 
-## Delegator
-
-```js
-{
-  "kind": 0,
-  "tags": [
-    ["p", <delegatee pubkey>, <approved kind for override>...],
-  ],
-  "content": <metadata>,
-  // ...
-}
-```
-
-- The `p` tag contains the delegatee's pubkey. Optional approved kinds for override can be appended. If no approved kinds are specified, it is considered unrestricted.
-  - MAY have multiple `p` tags.
+## `kind 0` event
 
+### Main Account
 
-## Delegatee
-
-```js
+```jsonc
 {
   "kind": 0,
   "tags": [
-    ["P", <delegator pubkey>],
-    ["alt", "delegation account"], // optional
+    ["p", "<persona account pubkey>", "<optional description>"],
   ],
-  "content": <empty or metadata override>,
   // ...
 }
 ```
 
-- The `P` tag contains the delegator's pubkey.
-  - MUST NOT have multiple `P` tags.
-- The `content` can be empty or an override of the delegator's metadata if it is approved by the delegator.
-
-## Validation
+- The `p` tag contains a persona account pubkey. The optional description can be added.
+  - It MAY have multiple `p` tags.
 
-If a delegator's kind-0 has no `p` tags, and a delegatee's kind-0 contains the delegator's `P` tag, it is considered an invalid delegation, and vice versa.
 
-## Client
+### Persona Account
 
-Client SHOULD use the delegator's pubkey along with the delegatee's pubkey when adding to or removing from the contact list.
-All delegatee stuff SHOULD be considered an override of the delegator's stuff if each kind is approved by the delegator.
