 1. Make a change to Rust code.
 2. Run ``just compile-and-test``. This will compile the Rust code, then run Rust and Python tests in the default version.
 
-There are also version-specific test commands (e.g. ``just test-3-14``) - run ``just help`` to see which ones.
+You can also run tests under specific Python versions by passing the version, e.g. ``just test-python 3.14``.
