+You can use the Web UI to subscribe to topics as well. Simply type in the topic name and click the *Subscribe* button.
+
+While subscribing, you have the option to enable desktop notifications, as well as background notifications. When you
+enable them for the first time, you will be prompted to allow notifications on your browser.
+
+- **Sound only**
+
+  If you don't enable browser notifications, a sound will play when a new notification comes in, and the tab title
+  will show the number of new notifications.
+
+- **Browser Notifications**
+
+  This requires an active ntfy tab to be open to receive notifications. These are typically instantaneous, and will
+  appear as a system notification. If you don't see these, check that your browser is allowed to show notifications
+  (for example in System Settings on macOS).
+
+  If you don't want to enable background notifications, pinning the ntfy tab on your browser is a good solution to leave
+  it running.
+
+- **Background Notifications**
+
+  This uses the [Web Push API](https://caniuse.com/push-api). You don't need an active ntfy tab open, but in some
+  cases you may need to keep your browser open.
