+# Telegram
+
+:::info
+Users can optionally configure personal notifications in their user settings.
+
+User notifications are separate from system notifications, and the available notification types are dependent on user permissions.
+:::
+
+## Configuration
+
+:::info
+In order to configure Telegram notifications, you first need to [create a bot](https://telegram.me/BotFather).
+
+Bots **cannot** initiate conversations with users, so users must have your bot added to a conversation in order to receive notifications.
+:::
+
+### Bot Username (optional)
+
+If this value is configured, users will be able to click a link to start a chat with your bot and configure their own personal notifications.
+
+The bot username should end with `_bot`, and the `@` prefix should be omitted.
+
+### Bot Authentication Token
+
+At the end of the bot creation process, [@BotFather](https://telegram.me/botfather) will provide an authentication token.
+
+### Chat ID
+
+To obtain your chat ID, simply create a new group chat, add [@get_id_bot](https://telegram.me/get_id_bot), and issue the `/my_id` command.
+
+### Send Silently (optional)
+
+Optionally, notifications can be sent silently. Silent notifications send messages without notification sounds.
