Hello Keith, We do have a solid developer guide here [1] that goes into the key concepts and processor development a bit. The next best thing is to use the supplied maven archetype to lay down the fundamental pieces. You can read a bit more about that here [2]. Finally something that is also quite helpful is looking at the standard processors to see if anything follows the pattern/problem you had in mind and which can serve as a good basis [3]
That said it is pretty wild that we do not have a good canonical 'Hello World Processor' tutorial created already. So created a JIRA to do that.
