+## Dev environment tips
+
+- use treefmt to format all files
+- keep new code consistent with the existing style
+
+### Python
+
+- make code `ruff` compliant
+- use pytest to test python code tests should be put in `tests` directory
+- dont use global state
+- use google style docstrings
+- use typer over argparse
