 ## Modifying Chats
 
-TODO: haven't figured this bit out yet. Can receive chat modifications tho.
+WA uses an encrypted form of communication to send chat/app updates. This has been implemented mostly and you can send the following updates:
+
+- Archive a chat
+  ``` ts
+  const lastMsgInChat = await getLastMessageInChat('123456@s.whatsapp.net') // implement this on your end
+  await conn.chatModify({ archive: true }, '123456@s.whatsapp.net', [lastMsgInChat])
+  ```
+- Mute/unmute a chat
+  ``` ts
+  // mute for 8 hours
+  await conn.chatModify({ mute: 8*60*60*1000 }, '123456@s.whatsapp.net', [])
+  // unmute
+  await conn.chatModify({ mute: null }, '123456@s.whatsapp.net', [])
+  ```
+- Mark a chat read/unread
+  ``` ts
+  const lastMsgInChat = await getLastMessageInChat('123456@s.whatsapp.net') // implement this on your end
+  // mark it unread
+  await conn.chatModify({ markRead: false }, '123456@s.whatsapp.net', [lastMsgInChat])
+  ```
+
+- Delete message for me
+  ``` ts
+  // mark it unread
+  await conn.chatModify(
+      { clear: { message: { id: 'ATWYHDNNWU81732J', fromMe: true } } }, 
+      '123456@s.whatsapp.net', 
+      []
+  )
+  ```
+
+Note: if you mess up one of your updates, WA can log you out of all your devices and you'll have to login again.
