+#### anbox-session-manager (shell script)
+
+Simple wrapper script to be added into desktop startup program configuration. This is a simple work around script. If `anbox-session-manager` Systemd service is launched _before_ X11 session, launching the X11 session fails for unknown reasons. This script ensures that X11 session is launched _before_ `anbox-session-manager` Systemd service.
