NuGet package to control Nintex workflows from a Third-party application

I'm looking at a few NuGet packages to control my Nintex workflows (start, stop, publish, ...) on SharePoint from a Third-party application. I'm mostly interested in using the "Nintex.Workflow.2016" package by Nintex, but unfortunately I have not been able to find any documentations for it and none of its classes have any summary to know what they are used for. Dose any one know any NuGet package to recommend or a document for the above package or even a better solution for my problem? 

Please take a look the screenshot for the package details name

Thanks!
