+Custom Emoji
+------------
+
+`draft` `optional` `author:alexgleason`
+
+Custom emoji may be added to **kind 0** and **kind 1** events by including one or more `"emoji"` tags, in the form:
+
+```
+["emoji", <shortcode>, <image-url>]
+```
+
+Where:
+
+- `<shortcode>` is a name given for the emoji, which MUST be comprised of only alphanumeric characters.
+- `<image-url>` is a URL to the corresponding image file of the emoji.
+
+For each emoji tag, clients should parse emoji shortcodes (aka "emojify") like `:shortcode:` in the event to display custom emoji.
+
+Clients may allow users to add custom emoji to an event by including `:shortcode:` identifier in the event, and adding the relevant `"emoji"` tags.
+
+### Kind 0 events
+
+In kind 0 events, the `name` and `about` fields should be emojified.
+
+```json
+{
+  "kind": 0,
+  "content": "{\"name\":\"Alex Gleason :soapbox:\"}",
+  "tags": [
+    ["emoji", "soapbox", "https://gleasonator.com/emoji/Gleasonator/soapbox.png"]
+  ],
+  "pubkey": "79c2cae114ea28a981e7559b4fe7854a473521a8d22a66bbab9fa248eb820ff6",
+  "created_at": 1682790000
+}
+```
+
+### Kind 1 events
+
+In kind 1 events, the `content` should be emojified.
+
+```json
+{
+  "kind": 1,
+  "content": "Hello :gleasonator: 😂 :ablobcatrainbow: :disputed: yolo",
+    "tags": [
+    ["emoji", "ablobcatrainbow", "https://gleasonator.com/emoji/blobcat/ablobcatrainbow.png"],
+    ["emoji", "disputed", "https://gleasonator.com/emoji/Fun/disputed.png"],
+    ["emoji", "gleasonator", "https://gleasonator.com/emoji/Gleasonator/gleasonator.png"]
+  ],
+  "pubkey": "79c2cae114ea28a981e7559b4fe7854a473521a8d22a66bbab9fa248eb820ff6",
+  "created_at": 1682630000
+}
