Thanks for your post. I'm not sure whether you have already found the below links, but there is some supporting information on our website that might help.
* Further information about NuGet packages and NuGet servers: http://www.red-gate.com/supportcenter/C ... t_packages
* 'Automated deployment using Red Gate tools' whitepaper, which describes an example Deployment Manager use case. Page 6 talks about Package-based deployment.
We are really keen to help you get set-up with Deployment Manager, so you can evaluate the product. So, please let me know if these help, and if you have any further questions or feedback.
