 Read the example usage on the [wiki](https://github.com/tsl0922/ttyd/wiki/Example-Usage).
 
+## Desktop Notification Bridging
+
+Pass `-N` (or `--monitor-notifications`) to forward desktop notifications to the browser:
+
+```
+ttyd -N -W bash
+```
+
+When enabled, ttyd registers as a D-Bus notification daemon on the session bus (falling back to the system bus on headless servers). Any application that sends notifications via `org.freedesktop.Notifications` will have them forwarded to all connected browser clients as native [Browser Notifications](https://developer.mozilla.org/en-US/docs/Web/API/Notification).
+
+If a notification daemon is already running (e.g. KDE Plasma, GNOME Shell), ttyd falls back to monitoring with `dbus-monitor`.
+
+Build requirement: `libsystemd-dev` (for `sd-bus`).
