+"""Module for the Mo1 Bragg positioner of the Debye beamline.
+The softIOC is reachable via the EPICS prefix X01DA-OP-MO1:BRAGG: and connected
+to a motor controller via web sockets. The Mo1 Bragg positioner is not only a
+positioner, but also a scan controller to setup XAS and XRD scans. A few scan modes
+are programmed in the controller, e.g. simple and advanced XAS scans + XRD triggering mode.
+
+Note: For some of the Epics PVs, in particular action buttons, the put_complete=True is
+used to ensure that the action is executed completely. This is believed
+to allow for a more stable execution of the action."""
