 This NIP defines two kinds:
 
-- `kind:0`: **User Metadata**: the `content` is set to a stringified JSON object `{name: <username>, about: <string>, picture: <url, string>}` describing the user who created the event. A relay may delete older events once it gets a new one for the same pubkey.
-- `kind:1`: **Text Note**: the `content` is set to the **plaintext** content of a note (anything the user wants to say). Content that must be parsed, such as Markdown and HTML, should not be used. Clients should also not parse content as those.
+- `kind:0`: **User Metadata**: An event kind to add name and other information to the pubkey. The `content` is set to a stringified JSON object `{name: <user's name, string>, about: <string>, picture: <url, string>}`
