-# Ditto custom events
-
-Instead of using database tables, the Ditto server publishes Nostr events that describe its state. It then reads these events using Nostr filters.
-
-## Ditto User (kind 30361)
-
-The Ditto server publishes kind `30361` events to represent users. These events are parameterized replaceable events of kind `30361` where the `d` tag is a pubkey. These events are published by Ditto's internal admin keypair.
-
-User events have the following tags:
-
-- `d` - pubkey of the user.
-- `role` - one of `admin` or `user`.
-
-Example:

-## NIP-78
-
-[NIP-78](https://github.com/nostr-protocol/nips/blob/master/78.md) defines events of kind `30078` with a globally unique `d` tag. These events are queried by the `d` tag, which allows Ditto to store custom data on relays. Ditto uses reverse DNS names like `pub.ditto.<thing>` for `d` tags.
-
-The sections below describe the `content` field. Some are encrypted and some are not, depending on whether the data should be public. Also, some events are user events, and some are admin events.
-
-### `pub.ditto.pleroma.config`
-
-NIP-04 encrypted JSON array of Pleroma ConfigDB objects. Pleroma admin API endpoints set this config, and Ditto reads from it.
