# Notes - Run tests with `-n12` for speed (e.g. `python -m pytest test/null/test_dtype.py -x -q -n12`) - Run `python -m mypy tinygrad/` to typecheck - Run `python -m ruff check .` to lint - Read `./tinygrad/viz/README.md` for profiling and debugging rewrite rules - Do not do amend commits. Always do a new commit if a force push to origin would be required.
