+# Local Chat
+
+There is one local chat on your Butter Box that is open to anyone who is
+able to join the box. If they can open the portal, they can open the chat
+and say or post anything they want. Depending on your use case, moderation
+capabilities may be important.
+
+First, let's look at what you can and can't do with this local chat.
+
+✅  **You Can**<br/>
+
+* Host videos up to 5 GB PDFs, images, record, audio messages, share
+  pre-recorded audio messages or music
+* Download the full chat or any individual piece of content or media that
+  people have shared
+
+❌  **You Cannot**<br/>
+
+* Use the chat to talk with people who are not connected to the Butter Box
+* Get notifications when there are new posts or messages
+* See the messages unless you are connected to the Butter Box
+
+
+
+## Moderation
+
+A Butter Box offers moderation features for the local chat. In order to
+access these features, you need to login as the admin of the room.
+
+### Become the Admin
+
+### Logout as Guest
+
+When you open the local chat, you are assigned a guest identity. First
+logout of the account that was created for you.
+
+### Login as Admin
+
+Login to the `butterbox-admin` account. Username and password are both
+`butterbox-admin`.
+
+### Change Admin Password
+
+Visit your user profile to change the password. At your discretion, you may
+also wish to change your display name so that other users will recognize
+you.
+
+### Moderation Features
+
+Once you are an admin, you have access to the following features:
+
+* **Set a message timer**
+* **Delete messages**
+* **Promote members to moderator or admin**
+* **Kick members out.**
+  * Keep in mind that someone can simply rejoin as a new guest if they
+    reconnect to the box
+* **Delete the room.**
+  * Warning: If you delete the room, you will no longer have a local chat on
+    your Butter Box. To get one back, you will have to flash a new image of
+    the Butter Box software to your SD card.
+
+
+
+## Say Even More—Direct Messages and Private Rooms
+
+In addition to the local chat, you can create any number of private rooms
+from the same interface.
+
+### Things To Know
+
+* Each room will have it's own QR code.
+* Private rooms are not discoverable from the Butter Box portal.
+* If you create a private room, you have to share the QR code physically to
+  whomever you want to join **who is also connected to the box.**
+* Every private chat that you are part of, will be easy for **you** to
+  find. They will all show up in your room list.
+
+### Instructions
+
+You can create a private room from two different places in the message board
+interface.
+
+### Open from Avatar Modal
+
+Tap on your avatar in the top bar. Select **new room.**
