Missing 1 required positional argument: `stages`

[hukai916]

Hi Jeff,

When running the knock-knock process command, I encountered the following error:

Traceback (most recent call last):
  File "/opt/conda/bin/knock-knock", line 236, in <module>
    args.func(args)
TypeError: process() missing 1 required positional argument: 'stages'

Also, in your example, it says:

knock-knock process PROJECT_DIR EXAMPLE_GROUP EXAMPLE_SAMPLE

What does EXAMPLE_SAMPLE mean? Can you provide some concrete example?

Thanks and best,

--Kai
