 ## Streaming
 
+### Chats
+
 There is an additional `user:pleroma_chat` stream. Incoming chat messages will make the current chat be sent to this `user` stream. The `event` of an incoming chat message is `pleroma:chat_update`. The payload is the updated chat with the incoming chat message in the `last_message` field.
 
+### Remote timelines
+
 For viewing remote server timelines, there are `public:remote` and `public:remote:media` streams. Each of these accept a parameter like `?instance=lain.com`.
 
+### Follow relationships updates
+
+Pleroma streams follow relationships updates as `pleroma:follow_relationships_update` events to the `user` stream.
+
+The message payload consist of:
+
+- `state`: a relationship state, one of `follow_pending`, `follow_accept` or `follow_reject`.
+
+- `follower` and `following` maps with following fields:
+  - `id`: user ID
+  - `follower_count`: follower count
+  - `following_count`: following count

 ## User muting and thread muting
 
 Both user muting and thread muting can be done for only a certain time by adding an `expires_in` parameter to the API calls and giving the expiration time in seconds.
