+To separate EXWM buffers from Emacs buffers in @code{helm-mini}, set up the sources as follows:
+@code{
+  (setq helm-exwm-emacs-buffers-source (helm-exwm-build-emacs-buffers-source))
+  (setq helm-exwm-source (helm-exwm-build-source))

+                                    helm-source-recentf)
+}
+@code{helm-exwm-switch} is a convenience X application launcher using Helm to
+switch between the various windows of one or several specific applications.
+See @code{helm-exwm-switch-browser} for an example.
