+A repost is a `kind 6` note that is used to signal to followers
+that another event is worth reading.
+
+The `content` of a repost event is empty.
+
+The repost event MUST include an `e` tag with the `id` of the note that is
+being reposted. That tag SHOULD include a relay URL as its third entry
+to indicate where it can be fetched.
+
+The repost SHOULD include a `p` tag with the `pubkey` of the event being
+reposted.
