+The **termdash.KeyboardSubscriber** function can be used by the developer to provide an additional subscriber to keyboard events. A keyboard subscriber is a function (a callback) that processes keyboard events. This function must be thread-safe, since Termdash delivers events concurrently. Providing an additional keyboard subscriber is completely optional and doesn't affect any of Termdash functionalities.
+
+The following example shows initialisation of Termdash with a keyboard subscriber that terminates the application when the letter 'q' or 'Q' is pressed on the keyboard.
+
+```go
+// Create terminal t and container c as in the examples above.
+
+// Context for Termdash, the application quits when this expires.
+// Since the context has no deadline, it will only expire when cancel() is called.
+ctx, cancel := context.WithCancel(context.Background())
+
+// A keyboard subscriber that terminates the application by cancelling the context.
+quitter := func(k *terminalapi.Keyboard) {
+  if k.Key == 'q' || k.Key == 'Q' {
+    cancel()
+  }
+}
+
+// Termdash will run until one of the two letters is pressed.
+if err := termdash.Run(ctx, t, c, termdash.KeyboardSubscriber(quitter)); err != nil {
+    return fmt.Errorf("termdash.Run => %v", err)
