Carry out a basic configuration of CUE itself and the nginx web server that serves the CUE application.
Configure nginx to support cross-origin communication between CUE and the CUE Content Store's web service
These mandatory configuration tasks are both described in Mandatory Tasks.
There are in addition a number of more or less optional configuration tasks that you may need to carry out, depending on your specific requirements. These tasks are described in Optional Tasks.
