OK great. The nice thing about the existing codebase is that the nifi-standard-processors module has a lot of really great examples that should help bring people up to speed, and they are generally pretty well unit tested. Certainly that's a good place to go for examples.
But if you run into any issues, let us know and I'm sure we'll get everything straightened out!
