+### Options
+
+#### [`dummy_variable_rgx`](#dummy_variable_rgx)
+
+A regular expression used to identify "dummy" variables, or those which should be ignored when evaluating
+(e.g.) unused-variable checks.
+
+**Default value**: `"^(_+|(_+[a-zA-Z0-9_]*[a-zA-Z0-9]+?))$"` (matches `_`, `__`, and `_var`, but not `_var_`)
+
+**Type**: `Regex`
+
+**Example usage**:

+```toml
+[tool.ruff]
+# Only ignore variables named "_".
+dummy_variable_rgx = "^_$"
+```
+
+---
+
+#### [`exclude`](#exclude)
+
+A list of file patterns to exclude from linting.
+
+Exclusions are based on globs, and can be either:
+
+- Single-path patterns, like `.mypy_cache` (to exclude any directory named `.mypy_cache` in the
+  tree), `foo.py` (to exclude any file named `foo.py`), or `foo_*.py` (to exclude any file matching
+  `foo_*.py` ).
+- Relative patterns, like `directory/foo.py` (to exclude that specific file) or `directory/*.py`
+  (to exclude any Python files in `directory`). Note that these paths are relative to the
+  project root (e.g., the directory containing your `pyproject.toml`).
+
+Note that you'll typically want to use [`extend_exclude`](#extend_exclude) to modify the excluded
+paths.
+
+**Default value**: `[".bzr", ".direnv", ".eggs", ".git", ".hg", ".mypy_cache", ".nox", ".pants.d", ".ruff_cache", ".svn", ".tox", ".venv", "__pypackages__", "_build", "buck-out", "build", "dist", "node_modules", "venv"]`
+
+**Type**: `Vec<FilePattern>`
+
+**Example usage**:
+
+```toml
+[tool.ruff]
+exclude = [".venv"]
+````
+
+---
+
+#### [`extend_exclude`](#extend_exclude)
+
+A list of file patterns to omit from linting, in addition to those specified by `exclude`.
+
+**Default value**: `[]`
+
+**Type**: `Vec<FilePattern>`
+
+**Example usage**:
+
+```toml
+[tool.ruff]
+# In addition to the standard set of exclusions, omit all tests, plus a specific file.
+extend-exclude = ["tests", "src/bad.py"]
+````
+
+---
+
+#### [`ignore`](#ignore)
+
+A list of check code prefixes to ignore. Prefixes can specify exact checks (like `F841`), entire
+categories (like `F`), or anything in between.
+
+When breaking ties between enabled and disabled checks (via `select` and `ignore`, respectively),
+more specific prefixes override less specific prefixes.
+
+**Default value**: `[]`
+
+**Type**: `Vec<CheckCodePrefix>`
+
+**Example usage**:
+
+```toml
+[tool.ruff]
+# Skip unused variable checks (`F841`).
