+### Configuration files are now resolved hierarchically ([#1190](https://github.com/charliermarsh/ruff/pull/1190))
+
+`pyproject.toml` files are now resolved hierarchically, such that for each Python file, we find
+the first `pyproject.toml` file in its path, and use that to determine its lint settings.
+
+See the [README](https://github.com/charliermarsh/ruff#pyprojecttoml-discovery) for more.

 responsible for converting `flake8` configuration files to Ruff's TOML format. This logic
 lives in `flake8_to_ruff/src/converter.rs`.
 
+To update the documentation for supported configuration options, run `cargo dev generate-options`.
