 ### Metadata
 
-- For "tags"/"hashtags" (i.e. categories or keywords of relevance for the listing) the `"t"` event tag should be used, as per [NIP-12](https://github.com/nostr-protocol/nips/blob/master/12.md).
-- For images, whether included in the markdown content or not, clients SHOULD use `image` tags as described in [NIP-58](https://github.com/nostr-protocol/nips/blob/master/58.md). This allows clients to display images in carousel format more easily.
