+# Telegram Notifications
+
+Setting up Telegram notifications takes 60 seconds.
+
+1. Start by navigating to https://t.me/dao_dao_notifier_bot and tapping the
+   `Start` button at the bottom.
+
+   On Mobile:
+
+   ![Telegram Mobile](/img/notifications/tg-start-mobile.jpg)
+
+   On Desktop:
+
+   ![Telegram Desktop](/img/notifications/tg-start-desktop.png)
+
+2. Once you tap the `Start` button, you should see instructions for tracking a
+   DAO.
+
+   On Mobile:
+
+   ![Telegram Mobile](/img/notifications/tg-started-mobile.jpg)
+
+   On Desktop:
+
+   ![Telegram Desktop](/img/notifications/tg-started-desktop.png)
+
+3. If you'd like to track DAOs with other people, add the bot to a group chat by
+   tapping its name at the top of the screen and then tapping the `Add to Group
+or Channel` button at the bottom.
+
+   When adding the bot to a group, it may ask if you want to make it an admin.
+   You do **_NOT_** need to do this. Adding it as a regular member is
+   sufficient. Also, it runs in privacy mode, so it can't read any of your
+   messages.
+
+   If you just want private notifications, skip this step.
+
+   On Mobile:
+
+   ![Telegram Mobile](/img/notifications/tg-add-group-mobile.jpg)
+
+   On Desktop:
+
+   ![Telegram Desktop](/img/notifications/tg-add-group-desktop.png)
+
+4. Once the bot is in the chat where you want to receive notifications, just
+   send the command shown in the instructions to start tracking a DAO. You can
+   also paste the entire DAO URL from your browser instead of typing the address
+   manually.
+
+   ```
+   /add@dao_dao_notifier_bot DAO_ADDRESS
+   ```
+
+   On Mobile:
+
+   ![Telegram Mobile](/img/notifications/tg-add-mobile.jpg)
+
+   On Desktop:
+
+   ![Telegram Desktop](/img/notifications/tg-add-desktop.png)
+
+5. Now you're done! When new proposals are created, the bot will message you
+   right away.
+
+   If you added the bot to a group, everyone in the group will start receiving
+   notifications.
+
+   If you added the bot to a private chat, you'll be the only one receiving
+   notifications.
+
+   You can track additional DAOs by sending the same command from any chat that
+   the bot is in.
