I’d like a bit of guidance - and maybe to suggest that the docs could be improved.

Looking at the [perimeter detect section of the zymkey docs](https://docs.zymbit.com/getting-started/zymkey4/production-mode/#prepare-perimeter-detect), the suggestion is that some python is ran to clear it. What’s confusing me is that I would expect this to be the default configuration. Is this just a safety measure incase the user has been changing the perimeter detect mode?

Also, since there are already a couple of tests python scripts in the install (e.g. /usr/local/share/zymkey/examples/zk\_app\_utils\_test.py)  
, might be good to have a script in there to disable the perimeter detect, rather than running inline python? Minor thing.

Just trying to understand this fully before I snip the board.
