+Notifications and privacy

+By default, Nextcloud Talk will notify you about:

+- New messages in private conversations;
+- Replies to messages you sent;
+- Messages mentioning you or group/team you are member of;
+- Started calls in conversations you are part of.
+
+You can change this behavior in the conversation settings. Additionally, you can configure:
+
+- **Important conversations**: you will be always notificed about new messages, even if you are in "Do Not Disturb" mode;
+- **Sensitive conversations**: content of messages will not be shown in the conversation list and obscured from notifications.

 Nextcloud Talk lets you chat and have video calls on your own server.
 
-Chats and calls take place in conversations. You can create any number of conversations. There are several kinds of conversations:
+Getting started
+---------------
 
-1. **One-on-one conversations.** This is where you have a private chat or call with another Talk user. You can't add other people to this conversation or share it with a link. You start a direct one-on-one chat by looking for another user in the search bar and then clicking their name. If a user becomes unavailable for long period and set an out-of-office status, you will find additional information in this conversation, such as provided description, absence date, or their replacement person.
+Chats and calls take place in conversations. You can create any number of conversations. There are different types of conversations:
+
+1. Private (one-to-one) conversations
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+This is where you have a private chat or call with another Talk user.
+
+In content sidebar, you can find additional information about the person you are chatting with, such as their email address, phone number, or other details they have shared in their profile.
+
+.. image:: images/one-to-one-right-sidebar.png

+
+Nobody except you and the other person can see this conversation or join a call in it.
+You can extend an ongoing call to a new group conversation by adding more people. Call will be continued there without interruption.

+
+2. Group conversations
+^^^^^^^^^^^^^^^^^^^^^^
+A group conversation can have any number of people in it.
+You can add internal users, email guests, groups or teams to a group conversation upon creation, or when it already exists, via the ``Participants`` tab.
+
+A group conversation can be shared with a public link, so guests can join a chat and a call.
+It can also be opened to registered users (or users from 'Guests' app), so they can discover and join this conversation.

-2. **Group conversations.** Besides the person who created the conversation, a group conversation can have any number of people in it. A group conversation can be shared publicly with a link, so external guest users can join a call. It can also be listed, so other people on your Nextcloud server can join the conversation.
+3. Note to self
+^^^^^^^^^^^^^^^
+This is a special conversation with yourself. Messages here do not have a limit for editing or deletion. You can use it to:
 
+- **Take notes**: write down ideas, reminders, or important information you want to keep handy.
+- **Create to-do lists**: use Markdown syntax to create checklists for tasks you need to complete.
+- **Forward messages from other chat**: use the message menu to forward important messages from other conversations to your Note to self.

+4. Disposable conversations
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+These conversations cover some special cases and exist for a limited period of time. Retention period can be configured by an instance administration:
+
+- **Instant meetings**: these conversations can be created for quick, ad-hoc meetings. They can be started instantly from the Talk Dashboard.
+- **Event conversations**: these are created when set as an event location by Calendar app.
+- **Phone conversations**: these are dedicated for SIP dial-in & dial-out phone calls (requires a SIP gateway).
+- **Video verification**: these are created, when someone tries to access a public link, protected by password with video verification (deleted instantly after call ends).

+Talk Dashboard
+--------------
+
+The Talk Dashboard is your central hub for managing and accessing your conversations. It provides an overview of your:
+
+- Unread mentions and messages in private chats;
+- Message reminders, scheduled to be tackled on later;
+- Scheduled meetings, with event details and shortcut buttons to join them;
+- Shortcut actions to create new conversations, join open ones, or quickly check your media devices.
