 mypy repo (so `..` refers to the mypy repo), there's a shortcut to run
 the mypy tests that avoids installing mypy:
 ```bash
-$ PYTHONPATH=.. python3 tests/mypy_test.py
+$ PYTHONPATH=../.. python3 tests/mypy_test.py
 ```
 You can mypy tests to a single version by passing `-p2` or `-p3.5` e.g.
 ```bash
-$ PYTHONPATH=.. python3 tests/mypy_test.py -p3.5
+$ PYTHONPATH=../.. python3 tests/mypy_test.py -p3.5
 running mypy --python-version 3.5 --strict-optional # with 342 files
