+## Formatting
+
+`kind:11` posts can be formatted like `kind:1` (with direct images, links and [NIP-27](27.md) references), but could also support [Djot](https://www.djot.net/).
+
+## Replies
+
 Replies to `kind 11` MUST use [NIP-22](./22.md) `kind 1111` comments. Replies should
 always be to the root `kind 11` to avoid arbitrarily nested reply hierarchies.
