 existing example, grep for `dummy_variable_rgx`, which defines a regular expression to match against
 acceptable unused variables (e.g., `_`).

+If the new plugin's configuration should be cached between runs, you'll need to add it to the
+`Hash` implementation for `Settings` in `src/settings/mod.rs`.
+
+You may also want to add the new configuration option to the `flake8-to-ruff` tool, which is

+lives in `flake8_to_ruff/src/converter.rs`.
