Production deployment of flowable engine

Hello,
I am working on a project that needs to embed a workflow engine\runtime and allow end-users to define their own workflows.
I am planning to build my own simplistic ui \ modeler that would allow the end users to define their workflows, and upload them to the workflow engine in runtime.

I’m evaluating flowable engine for this use case, and am wondering if there is any documentation, guidelines, practices or any other information on deploying flowable engine ?
