-As an example, the following would configure Ruff to: (1) enforce flake8-bugbear rules, in addition

-flake8-bugbear (`B`) violations; and (3) ignore import-at-top-of-file violations (`E402`) in
-`__init__.py` files:
-
-```toml
-[tool.ruff]
-# Enable flake8-bugbear (`B`) rules.
-select = ["E", "F", "B"]
-
-# Never enforce `E501` (line length violations).

-[tool.ruff.per-file-ignores]
-"__init__.py" = ["E402"]
-"path/to/file.py" = ["E402"]
-```
-
-Plugin configurations should be expressed as subsections, e.g.:
-
-```toml
-[tool.ruff]
-# Add "Q" to the list of enabled codes.
-select = ["E", "F", "Q"]
-
-[tool.ruff.flake8-quotes]
-docstring-quotes = "double"
-```
-
-Ruff mirrors Flake8's rule code system, in which each rule code consists of a one-to-three letter
-prefix, followed by three digits (e.g., `F401`). The prefix indicates that "source" of the rule
-(e.g., `F` for Pyflakes, `E` for pycodestyle, `ANN` for flake8-annotations). The set of enabled
-rules is determined by the `select` and `ignore` options, which support both the full code (e.g.,
-`F401`) and the prefix (e.g., `F`).
-
-As a special-case, Ruff also supports the `ALL` code, which enables all rules. Note that some of the
-pydocstyle rules conflict (e.g., `D203` and `D211`) as they represent alternative docstring
-formats. Enabling `ALL` without further configuration may result in suboptimal behavior, especially
-for the pydocstyle plugin.
-
-If you're wondering how to configure Ruff, here are some **recommended guidelines**:
-
-* Prefer `select` and `ignore` over `extend-select` and `extend-ignore`, to make your rule set
-  explicit.
-* Use `ALL` with discretion. Enabling `ALL` will implicitly enable new rules whenever you upgrade.
-* Start with a small set of rules (`select = ["E", "F"]`) and add a category at-a-time. For example,
-  you might consider expanding to `select = ["E", "F", "B"]` to enable the popular flake8-bugbear
-  extension.
-* By default, Ruff's autofix is aggressive. If you find that it's too aggressive for your liking,
-  consider turning off autofix for specific rules or categories (see: [FAQ](https://beta.ruff.rs/docs/faq/#ruff-tried-to-fix-something-but-it-broke-my-code-what-should-i-do)).
-
-### Configure via `ruff.toml`
-
-As an alternative to `pyproject.toml`, Ruff will also respect a `ruff.toml` file, which implements
-an equivalent schema (though the `[tool.ruff]` hierarchy can be omitted). For example, the
-`pyproject.toml` described above would be represented via the following `ruff.toml`:
-
-```toml
-# Enable flake8-bugbear (`B`) rules.
-select = ["E", "F", "B"]
-
-# Never enforce `E501` (line length violations).
-ignore = ["E501"]
-
-# Avoid trying to fix flake8-bugbear (`B`) violations.
-unfixable = ["B"]
-
-# Ignore `E402` (import violations) in all `__init__.py` files, and in `path/to/file.py`.

-### `pyproject.toml` discovery
-
-Similar to [ESLint](https://eslint.org/docs/latest/user-guide/configuring/configuration-files#cascading-and-hierarchy),
-Ruff supports hierarchical configuration, such that the "closest" `pyproject.toml` file in the
-directory hierarchy is used for every individual file, with all paths in the `pyproject.toml` file
-(e.g., `exclude` globs, `src` paths) being resolved relative to the directory containing the
-`pyproject.toml` file.
-
-There are a few exceptions to these rules:
-
-1. In locating the "closest" `pyproject.toml` file for a given path, Ruff ignores any
-   `pyproject.toml` files that lack a `[tool.ruff]` section.
-2. If a configuration file is passed directly via `--config`, those settings are used for across
-   files. Any relative paths in that configuration file (like `exclude` globs or `src` paths) are
-   resolved relative to the _current working directory_.
-3. If no `pyproject.toml` file is found in the filesystem hierarchy, Ruff will fall back to using
-   a default configuration. If a user-specific configuration file exists
-   at `${config_dir}/ruff/pyproject.toml`, that file will be used instead of the default
-   configuration, with `${config_dir}` being determined via the [`dirs`](https://docs.rs/dirs/4.0.0/dirs/fn.config_dir.html)
-   crate, and all relative paths being again resolved relative to the _current working directory_.
-4. Any `pyproject.toml`-supported settings that are provided on the command-line (e.g., via
-   `--select`) will override the settings in _every_ resolved configuration file.
-
-Unlike [ESLint](https://eslint.org/docs/latest/user-guide/configuring/configuration-files#cascading-and-hierarchy),
-Ruff does not merge settings across configuration files; instead, the "closest" configuration file
-is used, and any parent configuration files are ignored. In lieu of this implicit cascade, Ruff
-supports an [`extend`](https://beta.ruff.rs/docs/settings#extend) field, which allows you to inherit the settings from another
-`pyproject.toml` file, like so:
-
-```toml
-# Extend the `pyproject.toml` file in the parent directory.
-extend = "../pyproject.toml"
-# But use a different line length.
-line-length = 100
-```
-
-All of the above rules apply equivalently to `ruff.toml` files. If Ruff detects both a `ruff.toml`
-and `pyproject.toml` file, it will defer to the `ruff.toml`.
-
-### Python file discovery
-
-When passed a path on the command-line, Ruff will automatically discover all Python files in that
-path, taking into account the [`exclude`](https://beta.ruff.rs/docs/settings#exclude) and
-[`extend-exclude`](https://beta.ruff.rs/docs/settings#extend-exclude) settings in each directory's
-`pyproject.toml` file.
-
-By default, Ruff will also skip any files that are omitted via `.ignore`, `.gitignore`,
-`.git/info/exclude`, and global `gitignore` files (see: [`respect-gitignore`](https://beta.ruff.rs/docs/settings#respect-gitignore)).
-
-Files that are passed to `ruff` directly are always linted, regardless of the above criteria.
-For example, `ruff check /path/to/excluded/file.py` will always lint `file.py`.
-
-### Rule resolution
-
-The set of enabled rules is controlled via the [`select`](https://beta.ruff.rs/docs/settings#select)
-and [`ignore`](https://beta.ruff.rs/docs/settings#ignore) settings, along with the
-[`extend-select`](https://beta.ruff.rs/docs/settings#extend-select) and
-[`extend-ignore`](https://beta.ruff.rs/docs/settings#extend-ignore) modifiers.
-
-To resolve the enabled rule set, Ruff may need to reconcile `select` and `ignore` from a variety
-of sources, including the current `pyproject.toml`, any inherited `pyproject.toml` files, and the
-CLI (e.g., `--select`).
-
-In those scenarios, Ruff uses the "highest-priority" `select` as the basis for the rule set, and
-then applies any `extend-select`, `ignore`, and `extend-ignore` adjustments. CLI options are given
-higher priority than `pyproject.toml` options, and the current `pyproject.toml` file is given higher
-priority than any inherited `pyproject.toml` files.
-
-For example, given the following `pyproject.toml` file:
-
-```toml
-[tool.ruff]
-select = ["E", "F"]
-ignore = ["F401"]
-```
-
-Running `ruff check --select F401` would result in Ruff enforcing `F401`, and no other rules.
-
-Running `ruff check --extend-select B` would result in Ruff enforcing the `E`, `F`, and `B` rules, with
-the exception of `F401`.
-
-### Suppressing errors
-
-To omit a lint rule entirely, add it to the "ignore" list via [`ignore`](https://beta.ruff.rs/docs/settings#ignore)
-or [`extend-ignore`](https://beta.ruff.rs/docs/settings#extend-ignore), either on the command-line
-or in your `pyproject.toml` file.
-
-To ignore a violation inline, Ruff uses a `noqa` system similar to [Flake8](https://flake8.pycqa.org/en/3.1.1/user/ignoring-errors.html).
-To ignore an individual violation, add `# noqa: {code}` to the end of the line, like so:
-
-```python
-# Ignore F841.
-x = 1  # noqa: F841
-
-# Ignore E741 and F841.
-i = 1  # noqa: E741, F841
-
-# Ignore _all_ violations.
-x = 1  # noqa
-```
-
-Note that, for multi-line strings, the `noqa` directive should come at the end of the string, and
-will apply to the entire string, like so:
-
-```python
-"""Lorem ipsum dolor sit amet.
-
-Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor.
-"""  # noqa: E501
-```
-
-To ignore all violations across an entire file, add `# ruff: noqa` to any line in the file, like so:
-
-```python
-# ruff: noqa
-```
-
-To ignore a specific rule across an entire file, add `# ruff: noqa: {code}` to any line in the file,
-like so:
-
-```python
-# ruff: noqa: F841
-```
-
-Or see the [`per-file-ignores`](https://beta.ruff.rs/docs/settings#per-file-ignores) configuration
-setting, which enables the same functionality via a `pyproject.toml` file.
-
-Note that Ruff will also respect Flake8's `# flake8: noqa` directive, and will treat it as
-equivalent to `# ruff: noqa`.
-
-#### Automatic error suppression
-
-Ruff supports several workflows to aid in `noqa` management.
-
-First, Ruff provides a special rule code, `RUF100`, to enforce that your `noqa` directives are
-"valid", in that the violations they _say_ they ignore are actually being triggered on that line (and
-thus suppressed). You can run `ruff check /path/to/file.py --extend-select RUF100` to flag unused `noqa`
-directives.
-
-Second, Ruff can _automatically remove_ unused `noqa` directives via its autofix functionality.
-You can run `ruff check /path/to/file.py --extend-select RUF100 --fix` to automatically remove unused
-`noqa` directives.
-
-Third, Ruff can _automatically add_ `noqa` directives to all failing lines. This is useful when
-migrating a new codebase to Ruff. You can run `ruff check /path/to/file.py --add-noqa` to automatically
-add `noqa` directives to all failing lines, with the appropriate rule codes.
-
-#### Action comments
-
-Ruff respects `isort`'s [action comments](https://pycqa.github.io/isort/docs/configuration/action_comments.html)
-(`# isort: skip_file`, `# isort: on`, `# isort: off`, `# isort: skip`, and `# isort: split`), which
-enable selectively enabling and disabling import sorting for blocks of code and other inline
-configuration.
-
-See the [`isort` documentation](https://pycqa.github.io/isort/docs/configuration/action_comments.html)
-for more.
-
-### Exit codes
-
-By default, Ruff exits with the following status codes:
-
-* `0` if no violations were found, or if all present violations were fixed automatically.
-* `1` if violations were found.
-* `2` if Ruff terminates abnormally due to invalid configuration, invalid CLI options, or an internal error.
-
-This convention mirrors that of tools like ESLint, Prettier, and RuboCop.
-
-Ruff supports two command-line flags that alter its exit code behavior:
-
-* `--exit-zero` will cause Ruff to exit with a status code of `0` even if violations were found.
-  Note that Ruff will still exit with a status code of `2` if it terminates abnormally.
-* `--exit-non-zero-on-fix` will cause Ruff to exit with a status code of `1` if violations were
-  found, _even if_ all such violations were fixed automatically. Note that the use of
-  `--exit-non-zero-on-fix` can result in a non-zero exit code even if no violations remain after
-  autofixing.

-
-Ruff supports autocompletion for most shells. A shell-specific completion script can be generated
-by `ruff generate-shell-completion <SHELL>`, where `<SHELL>` is one of `bash`, `elvish`, `fig`, `fish`,
-`powershell`, or `zsh`.
-
-The exact steps required to enable autocompletion will vary by shell. For example instructions,
-see the [Poetry](https://python-poetry.org/docs/#enable-tab-completion-for-bash-fish-or-zsh) or
-[ripgrep](https://github.com/BurntSushi/ripgrep/blob/master/FAQ.md#complete) documentation.
-
-As an example: to enable autocompletion for Zsh, run
-`ruff generate-shell-completion zsh > ~/.zfunc/_ruff`. Then add the following line to your
-`~/.zshrc` file, if they're not already present:
-
-```zsh
-fpath+=~/.zfunc
-autoload -Uz compinit && compinit
-```

 Rust as a first-party feature.
 
 By default, Ruff enables Flake8's `E` and `F` rules. Ruff supports all rules from the `F` category,
 and a [subset](https://beta.ruff.rs/docs/rules/#error-e) of the `E` category, omitting those
