Thanks for the PR, was almost a perfect PR, just a few tips. Whenever you see a pull request template or any other template in the docs folder in any github repository, those are automatically used when you open an issue or new PR. You'll edit it when you make the PR or open an issue, you don't edit the file itself, it will auto populate for you as markdown.

It is most convenient to do patches on branches rather than master.

Lastly is to rev up the version number on init.py but don't worry I'll work on a more formal document on how to create a PR for pylogix.

I made a small modification to the example so we can still show the user, all the bits of information possible with the returned value.
