 ### Running Python Code Formatter
 
-We're using a tool called [black](https://github.com/ambv/black) on this repo to ensure consistent formatting. On CI it runs in "check" mode to ensure any new files added to the repo are following PEP 8. If you see linter warnings that say something like "would reformat some_file.py" it means black disagrees with your formatting.
