this document describes, based on what's in Qlik Sense 2.0.1, some of the main capabilities of the Qlik Deployment Console. You can see how to create one or many multi node sites and how you can use the QDC as well for transferring content in between of them.
I will upload a new version shortly for 2.1 which will talk about some new capabilities. And there is much more to come ...
Please let me know if you have questions or any other type of feedback.
