Deployment Guidelines
=====================

`slsDetectors` will automatically install its dependency
`slsDetectorsPackage`.

For debugging purposes it can be useful to have ``tshark`` installed on the
control server, and ``xctrl`` user added to the ``wireshark`` group.

The control server should have a 10 GbE network interface for sending images
to the DAQ, and possibly one for the GUI server.
