-# Breaking Changes
-
-## 0.0.246
-
-### `multiple-statements-on-one-line-def` (`E704`) was removed ([#2773](https://github.com/charliermarsh/ruff/pull/2773))
-
-This rule was introduced in v0.0.245. However, it turns out that pycodestyle and Flake8 ignore this
-rule by default, as it is not part of PEP 8. As such, we've removed it from Ruff.
-
-## 0.0.245
-
-### Ruff's public `check` method was removed ([#2709](https://github.com/charliermarsh/ruff/pull/2709))
-
-Previously, Ruff exposed a `check` method as a public Rust API. This method was used by few,
-if any clients, and was not well documented or supported. As such, it has been removed, with
-the intention of adding a stable public API in the future.
-
-## 0.0.238
-
-### `select`, `extend-select`, `ignore`, and `extend-ignore` have new semantics ([#2312](https://github.com/charliermarsh/ruff/pull/2312))
-
-Previously, the interplay between `select` and its related options could lead to unexpected
-behavior. For example, `ruff --select E501 --ignore ALL` and `ruff --select E501 --extend-ignore ALL` behaved differently. (See [#2312](https://github.com/charliermarsh/ruff/pull/2312) for more
-examples.)
-
-When Ruff determines the enabled rule set, it has to reconcile `select` and `ignore` from a variety
-of sources, including the current `pyproject.toml`, any inherited `pyproject.toml` files, and the
-CLI.
-
-The new semantics are such that 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.
-
-`extend-select` and `extend-ignore` are no longer given "top priority"; instead, they merely append
-to the `select` and `ignore` lists, as in Flake8.
-
-This change is largely backwards compatible -- most users should experience no change in behavior.
-However, as an example of a breaking change, consider the following:
-
-```toml
-[tool.ruff]
-ignore = ["F401"]
-```
-
-Running `ruff --select F` would previously have enabled all `F` rules, apart from `F401`. Now, it
-will enable all `F` rules, including `F401`, as the command line's `--select` resets the resolution.
-
-### `remove-six-compat` (`UP016`) has been removed ([#2332](https://github.com/charliermarsh/ruff/pull/2332))
-
-The `remove-six-compat` rule has been removed. This rule was only useful for one-time Python 2-to-3
-upgrades.
-
-## 0.0.237
-
-### `--explain`, `--clean`, and `--generate-shell-completion` are now subcommands ([#2190](https://github.com/charliermarsh/ruff/pull/2190))
-
-`--explain`, `--clean`, and `--generate-shell-completion` are now implemented as subcommands:
-
-```console
-ruff .         # Still works! And will always work.
-ruff check .   # New! Also works.
-
-ruff --explain E402   # Still works.
-ruff rule E402        # New! Also works. (And preferred.)
-
-# Oops! The command has to come first.
-ruff --format json --explain E402   # No longer works.
-ruff --explain E402 --format json   # Still works!
-ruff rule E402   --format json      # Works! (And preferred.)
-```
-
-This change is largely backwards compatible -- most users should experience
-no change in behavior. However, please note the following exceptions:
-
-- Subcommands will now fail when invoked with unsupported arguments, instead
-  of silently ignoring them. For example, the following will now fail:
-
-  ```console
-  ruff --clean --respect-gitignore
-  ```
-
-  (the `clean` command doesn't support `--respect-gitignore`.)
-
-- The semantics of `ruff <arg>` have changed slightly when `<arg>` is a valid subcommand.
-  For example, prior to this release, running `ruff rule` would run `ruff` over a file or
-  directory called `rule`. Now, `ruff rule` would invoke the `rule` subcommand. This should
-  only impact projects with files or directories named `rule`, `check`, `explain`, `clean`,
-  or `generate-shell-completion`.
-
-- Scripts that invoke ruff should supply `--` before any positional arguments.
-  (The semantics of `ruff -- <arg>` have not changed.)
-
-- `--explain` previously treated `--format grouped` as a synonym for `--format text`.
-  This is no longer supported; instead, use `--format text`.
-
-## 0.0.226
-
-### `misplaced-comparison-constant` (`PLC2201`) was deprecated in favor of `SIM300` ([#1980](https://github.com/charliermarsh/ruff/pull/1980))
-
-These two rules contain (nearly) identical logic. To deduplicate the rule set, we've upgraded
-`SIM300` to handle a few more cases, and deprecated `PLC2201` in favor of `SIM300`.
-
-## 0.0.225
-
-### `@functools.cache` rewrites have been moved to a standalone rule (`UP033`) ([#1938](https://github.com/charliermarsh/ruff/pull/1938))
-
-Previously, `UP011` handled both `@functools.lru_cache()`-to-`@functools.lru_cache` conversions,
-_and_ `@functools.lru_cache(maxsize=None)`-to-`@functools.cache` conversions. The latter has been
-moved out to its own rule (`UP033`). As such, some `# noqa: UP011` comments may need to be updated
-to reflect the change in rule code.
-
-## 0.0.222
-
-### `--max-complexity` has been removed from the CLI ([#1877](https://github.com/charliermarsh/ruff/pull/1877))
-
-The McCabe plugin's `--max-complexity` setting has been removed from the CLI, for consistency with
-the treatment of other, similar settings.
-
-To set the maximum complexity, use the `max-complexity` property in your `pyproject.toml` file,
-like so:
-
-```toml
-[tool.ruff.mccabe]
-max-complexity = 10
-```
-
-## 0.0.181
-
-### Files excluded by `.gitignore` are now ignored ([#1234](https://github.com/charliermarsh/ruff/pull/1234))
-
-Ruff will now avoid checking files that are excluded by `.ignore`, `.gitignore`,
-`.git/info/exclude`, and global `gitignore` files. This behavior is powered by the [`ignore`](https://docs.rs/ignore/latest/ignore/struct.WalkBuilder.html#ignore-rules)
-crate, and is applied in addition to Ruff's built-in `exclude` system.
-
-To disable this behavior, set `respect-gitignore = false` in your `pyproject.toml` file.
-
-Note that hidden files (i.e., files and directories prefixed with a `.`) are _not_ ignored by
-default.
-
-## 0.0.178
-
-### 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.

 ### Prerequisites
 
-Ruff is written in Rust. You'll need to install the
+ruff is written in Rust (1.63.0). You'll need to install the
 [Rust toolchain](https://www.rust-lang.org/tools/install) for development.
 
-You'll also need [Insta](https://insta.rs/docs/) to update snapshot tests:
-
-```shell
-cargo install cargo-insta
-```
-
 ### Development
 
-After cloning the repository, run Ruff locally with:
+After cloning the repository, run ruff locally with:
 
 ```shell
-cargo run -p ruff_cli -- check /path/to/file.py --no-cache
+cargo run resources/test/fixtures --no-cache
 ```
 
-Prior to opening a pull request, ensure that your code has been auto-formatted,
-and that it passes both the lint and test validation checks:

+cargo clippy  # Linting...
+cargo test    # Testing...
 ```
 
 These checks will run on GitHub Actions when you open your Pull Request, but running them locally
 will save you time and expedite the merge process.
 
-Note that many code changes also require updating the snapshot tests, which is done interactively
-after running `cargo test` like so:
-
-```shell
-cargo insta review
-```
-
-If you have `pre-commit` [installed](https://pre-commit.com/#installation) then you can use it to
-assist with formatting and linting. The following command will run the `pre-commit` hooks:
-
-```shell
-pre-commit run --all-files
-```
-
 Your Pull Request will be reviewed by a maintainer, which may involve a few rounds of iteration
 prior to merging.
 
-### Project Structure
-
-Ruff is structured as a monorepo with a [flat crate structure](https://matklad.github.io/2021/08/22/large-rust-workspaces.html),
-such that all crates are contained in a flat `crates` directory.
-
-The vast majority of the code, including all lint rules, lives in the `ruff` crate (located at
-`crates/ruff`). As a contributor, that's the crate that'll be most relevant to you.
-
-At time of writing, the repository includes the following crates:
-
-- `crates/ruff`: library crate containing all lint rules and the core logic for running them.
-- `crates/ruff_cli`: binary crate containing Ruff's command-line interface.
-- `crates/ruff_dev`: binary crate containing utilities used in the development of Ruff itself (e.g., `cargo dev generate-all`).
-- `crates/ruff_macros`: library crate containing macros used by Ruff.
-- `crates/ruff_python`: library crate implementing Python-specific functionality (e.g., lists of standard library modules by versionb).
-- `crates/flake8_to_ruff`: binary crate for generating Ruff configuration from Flake8 configuration.
-
 ### Example: Adding a new lint rule
 
-At a high level, the steps involved in adding a new lint rule are as follows:
+There are three phases to adding a new lint rule:
 
-1. Determine a name for the new rule as per our [rule naming convention](#rule-naming-convention).
-1. Create a file for your rule (e.g., `crates/ruff/src/rules/flake8_bugbear/rules/abstract_base_class.rs`).
-1. In that file, define a violation struct. You can grep for `define_violation!` to see examples.
-1. Map the violation struct to a rule code in `crates/ruff/src/registry.rs` (e.g., `E402`).
-1. Define the logic for triggering the violation in `crates/ruff/src/checkers/ast.rs` (for AST-based
-   checks), `crates/ruff/src/checkers/tokens.rs` (for token-based checks), `crates/ruff/src/checkers/lines.rs`
-   (for text-based checks), or `crates/ruff/src/checkers/filesystem.rs` (for filesystem-based
-   checks).
-1. Add a test fixture.
-1. Update the generated files (documentation and generated code).
+1. Define the rule in `src/checks.rs`.
+2. Define the _logic_ for triggering the rule in `src/check_ast.rs` (for AST-based checks)
+   or `src/check_lines.rs` (for text-based checks).
+3. Add a test fixture.
 
-To define the violation, start by creating a dedicated file for your rule under the appropriate
-rule linter (e.g., `crates/ruff/src/rules/flake8_bugbear/rules/abstract_base_class.rs`). That file should
-contain a struct defined via `define_violation!`, along with a function that creates the violation
-based on any required inputs. (Many of the existing examples live in `crates/ruff/src/violations.rs`,
-but we're looking to place new rules in their own files.)
+To define the rule, open up `src/checks.rs`. You'll need to define both a `CheckCode` and
+`CheckKind`. As an example, you can grep for `E402` and `ModuleImportNotAtTopOfFile`, and follow the
+pattern implemented therein.
 
-To trigger the violation, you'll likely want to augment the logic in `crates/ruff/src/checkers/ast.rs`,
-which defines the Python AST visitor, responsible for iterating over the abstract syntax tree and
-collecting diagnostics as it goes.

+the Python AST visitor, responsible for iterating over the abstract syntax tree and collecting
+lint-rule violations as it goes. Grep for the `Check::new` invocations to understand how other,
+similar rules are implemented.
 
-If you need to inspect the AST, you can run `cargo dev print-ast` with a Python file. Grep
-for the `Check::new` invocations to understand how other, similar rules are implemented.
+To add a test fixture, create a file under `resources/test/fixtures`, named to match the `CheckCode`
+you defined earlier (e.g., `E402.py`). This file should contain a variety of violations and
+non-violations designed to evaluate and demonstrate the behavior of your lint rule. Run ruff locally
+with (e.g.) `cargo run resources/test/fixtures/E402.py`. Once you're satisified with the output,
+codify the behavior as a snapshot test by adding a new function to the `mod tests` section of
+`src/linter.rs`, like so:
 
-To add a test fixture, create a file under `crates/ruff/resources/test/fixtures/[linter]`, named to match
-the code you defined earlier (e.g., `crates/ruff/resources/test/fixtures/pycodestyle/E402.py`). This file should
-contain a variety of violations and non-violations designed to evaluate and demonstrate the behavior
-of your lint rule.
+```rust
+#[test]
+fn e402() -> Result<()> {
+    let mut checks = check_path(
+        Path::new("./resources/test/fixtures/E402.py"),
+        &settings::Settings::for_rule(CheckCode::E402),
+        &fixer::Mode::Generate,
+    )?;
+    checks.sort_by_key(|check| check.location);
+    insta::assert_yaml_snapshot!(checks);
+    Ok(())
+}
+```
 
-Run `cargo dev generate-all` to generate the code for your new fixture. Then run Ruff
-locally with (e.g.) `cargo run -p ruff_cli -- check crates/ruff/resources/test/fixtures/pycodestyle/E402.py --no-cache --select E402`.
-
-Once you're satisfied with the output, codify the behavior as a snapshot test by adding a new
-`test_case` macro in the relevant `crates/ruff/src/[linter]/mod.rs` file. Then, run `cargo test`.
-Your test will fail, but you'll be prompted to follow-up with `cargo insta review`. Accept the
-generated snapshot, then commit the snapshot file alongside the rest of your changes.
-
-Finally, regenerate the documentation and generated code with `cargo dev generate-all`.
-
-#### Rule naming convention
-
-The rule name should make sense when read as "allow _rule-name_" or "allow _rule-name_ items".
-
-This implies that rule names:
-
-- should state the bad thing being checked for
-
-- should not contain instructions on what you what you should use instead
-  (these belong in the rule documentation and the `autofix_title` for rules that have autofix)
-
-When re-implementing rules from other linters, this convention is given more importance than
-preserving the original rule name.
+Then, run `cargo test`. Your test will fail, but you'll be prompted to follow-up with
+`cargo insta review`. Accept the generated snapshot, then commit the snapshot file alongside the
+rest of your changes.
 
 ### Example: Adding a new configuration option
 
-Ruff's user-facing settings live in a few different places.
+ruff's user-facing settings live in two places: first, the command-line options defined with
+[clap](https://docs.rs/clap/latest/clap/) via the `Cli` struct in `src/main.rs`; and second, the
+`Config` struct defined `src/pyproject.rs`, which is responsible for extracting user-defined
+settings from a `pyproject.toml` file.
 
-First, the command-line options are defined via the `Cli` struct in `crates/ruff/src/cli.rs`.
+Ultimately, these two sources of configuration are merged into the `Settings` struct defined
+in `src/settings.rs`, which is then threaded through the codebase.
 
-Second, the `pyproject.toml` options are defined in `crates/ruff/src/settings/options.rs` (via the
-`Options` struct), `crates/ruff/src/settings/configuration.rs` (via the `Configuration` struct), and
-`crates/ruff/src/settings/mod.rs` (via the `Settings` struct). These represent, respectively: the
-schema used to parse the `pyproject.toml` file; an internal, intermediate representation; and the
-final, internal representation used to power Ruff.
+To add a new configuration option, you'll likely want to _both_ add a CLI option to `src/main.rs`
+_and_ a `pyproject.toml` parameter to `src/pyproject.rs`. If you want to pattern-match against an
+existing example, grep for `dummy_variable_rgx`, which defines a regular expression to match against
+acceptable unused variables (e.g., `_`).
 
-To add a new configuration option, you'll likely want to modify these latter few files (along with
-`cli.rs`, if appropriate). If you want to pattern-match against an existing example, grep for
-`dummy_variable_rgx`, which defines a regular expression to match against acceptable unused
-variables (e.g., `_`).
+## Release process
 
-Note that plugin-specific configuration options are defined in their own modules (e.g.,
-`crates/ruff/src/flake8_unused_arguments/settings.rs`).
-
-You may also want to add the new configuration option to the `flake8-to-ruff` tool, which is
-responsible for converting `flake8` configuration files to Ruff's TOML format. This logic
-lives in `crates/ruff/src/flake8_to_ruff/converter.rs`.
-
-Finally, regenerate the documentation and generated code with `cargo dev generate-all`.
-
-## MkDocs

-
-```shell
-rm Lib/test/bad_coding.py \
-  Lib/test/bad_coding2.py \
-  Lib/test/bad_getattr.py \

-[**Sebastián Ramírez**](https://twitter.com/tiangolo/status/1591912354882764802), creator
-of [FastAPI](https://github.com/tiangolo/fastapi):
-
-> Ruff is so fast that sometimes I add an intentional bug in the code just to confirm it's actually
-> running and checking the code.
-
-[**Nick Schrock**](https://twitter.com/schrockn/status/1612615862904827904), founder of [Elementl](https://www.elementl.com/),
-co-creator of [GraphQL](https://graphql.org/):
-
-> Why is Ruff a gamechanger? Primarily because it is nearly 1000x faster. Literally. Not a typo. On
-> our largest module (dagster itself, 250k LOC) pylint takes about 2.5 minutes, parallelized across 4
-> cores on my M1. Running ruff against our _entire_ codebase takes .4 seconds.
-
-[**Bryan Van de Ven**](https://github.com/bokeh/bokeh/pull/12605), co-creator
-of [Bokeh](https://github.com/bokeh/bokeh/), original author
-of [Conda](https://docs.conda.io/en/latest/):
-
-> Ruff is ~150-200x faster than flake8 on my machine, scanning the whole repo takes ~0.2s instead of
-> ~20s. This is an enormous quality of life improvement for local dev. It's fast enough that I added
-> it as an actual commit hook, which is terrific.
-
-[**Timothy Crosley**](https://twitter.com/timothycrosley/status/1606420868514877440),
-creator of [isort](https://github.com/PyCQA/isort):
-
-> Just switched my first project to Ruff. Only one downside so far: it's so fast I couldn't believe it was working till I intentionally introduced some errors.
-
-[**Tim Abbott**](https://github.com/charliermarsh/ruff/issues/465#issuecomment-1317400028), lead
-developer of [Zulip](https://github.com/zulip/zulip):
-
-> This is just ridiculously fast... `ruff` is amazing.

+  - repo: https://github.com/charliermarsh/ruff-pre-commit
+    rev: v0.0.48
+    hooks:
+      - id: lint
 ```
 
-Ruff can also be used as a [VS Code extension](https://github.com/charliermarsh/ruff-vscode) or
-alongside any other editor through the [Ruff LSP](https://github.com/charliermarsh/ruff-lsp).
+## Configuration
 
-### Configuration
+ruff is configurable both via `pyproject.toml` and the command line.
 
-Ruff can be configured through a `pyproject.toml`, `ruff.toml`, or `.ruff.toml` file (see:
-[_Configuration_](https://beta.ruff.rs/docs/configuration/), or [_Settings_](https://beta.ruff.rs/docs/settings/)
-for a complete list of all configuration options).
-
-If left unspecified, the default configuration is equivalent to:
+For example, you could configure ruff to only enforce a subset of rules with:
 
 ```toml
 [tool.ruff]
-# Enable pycodestyle (`E`) and Pyflakes (`F`) codes by default.
-select = ["E", "F"]
-ignore = []
-
-# Allow autofix for all enabled rules (when `--fix`) is provided.
-fixable = ["A", "B", "C", "D", "E", "F", "..."]
-unfixable = []
-
-# Exclude a variety of commonly ignored directories.
-exclude = [
-    ".bzr",
-    ".direnv",
-    ".eggs",
-    ".git",
-    ".hg",
-    ".mypy_cache",
-    ".nox",
-    ".pants.d",
-    ".pytype",
-    ".ruff_cache",
-    ".svn",
-    ".tox",
-    ".venv",
-    "__pypackages__",
-    "_build",
-    "buck-out",
-    "build",
-    "dist",
-    "node_modules",
-    "venv",
-]
-
-# Same as Black.
 line-length = 88
-
-# Allow unused variables when underscore-prefixed.
-dummy-variable-rgx = "^(_+|(_+[a-zA-Z0-9_]*[a-zA-Z0-9]+?))$"
-
-# Assume Python 3.10.
-target-version = "py310"
-
-[tool.ruff.mccabe]
-# Unlike Flake8, default to a complexity level of 10.
-max-complexity = 10
+select = [
+    "F401",
+    "F403",
+]
 ```
 
-Some configuration options can be provided via the command-line, such as those related to
-rule enablement and disablement, file discovery, logging level, and more:
+Alternatively, on the command-line:
 
 ```shell
-ruff check path/to/code/ --select F401 --select F403 --quiet
+ruff path/to/code/ --select F401 --select F403
 ```
 
-See `ruff help` for more on Ruff's top-level commands, or `ruff help check` for more on the
-linting command.

+
+### Excluding files
+
+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`).
+
+### Ignoring errors
+
+To omit a lint check entirely, add it to the "ignore" list via `--ignore` or `--extend-ignore`,
+either  on the command-line or in your `project.toml` file.
+
+To ignore an error in-line, ruff uses a `noqa` system similar to [Flake8](https://flake8.pycqa.org/en/3.1.1/user/ignoring-errors.html).
+To ignore an individual error, 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_ errors.
+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 body, like so:
+
+```python
+"""Lorem ipsum dolor sit amet.
+
+Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
+"""  # noqa: E501
+```
+
+ruff supports several (experimental) workflows to aid in `noqa` management.
+
+First, ruff provides a special error code, `M001`, to enforce that your `noqa` directives are
+"valid", in that the errors they _say_ they ignore are actually being triggered on that line (and
+thus suppressed). **You can run `ruff /path/to/file.py --extend-select M001` to flag unused `noqa`
+directives.**
+
+Second, ruff can _automatically remove_ unused `noqa` directives via its autofix functionality.
+**You can run `ruff /path/to/file.py --extend-select M001 --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 /path/to/file.py --add-noqa` to automatically
+add `noqa` directives to all failing lines, with the appropriate error codes.**
+
+### Compatibility with Black
+
+ruff is compatible with [Black](https://github.com/psf/black) out-of-the-box, as long as
+the `line-length` setting is consistent between the two.
+
+As a project, ruff is designed to be used alongside Black and, as such, will defer implementing
+stylistic lint rules that are obviated by autoformatting.
+
+### Parity with Flake8
+
+ruff's goal is to achieve feature parity with Flake8 when used (1) without plugins, (2) alongside
+Black, and (3) on Python 3 code.
+
+**Under those conditions, ruff implements 44 out of 60 rules.** (ruff is missing: 14 rules related
+to string `.format` calls, 1 rule related to docstring parsing, and 1 rule related to redefined
+variables.)
+
+ruff also implements some of the most popular Flake8 plugins natively, including:
+
+- [`flake8-builtins`](https://pypi.org/project/flake8-builtins/)
+- [`flake8-super`](https://pypi.org/project/flake8-super/)
+- [`flake8-print`](https://pypi.org/project/flake8-print/)
+- [`pyupgrade`](https://pypi.org/project/pyupgrade/) (partial)
+
+Beyond rule-set parity, ruff suffers from the following limitations vis-à-vis Flake8:
+
+1. ruff does not yet support a few Python 3.9 and 3.10 language features, including structural
+   pattern matching and parenthesized context managers.
+2. Flake8 has a plugin architecture and supports writing custom lint rules.
 
 ## Rules
 
-<!-- Begin section: Rules -->
+The ✅ emoji indicates a rule is enabled by default.
 
-**Ruff supports over 500 lint rules**, many of which are inspired by popular tools like Flake8,
-isort, pyupgrade, and others. Regardless of the rule's origin, Ruff re-implements every rule in
-Rust as a first-party feature.
+The 🛠 emoji indicates that a rule is automatically fixable by the `--fix` command-line option.
 
-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
-stylistic rules made obsolete by the use of an autoformatter, like
-[Black](https://github.com/psf/black).

-## Acknowledgements
+## Development
 
-Ruff's linter draws on both the APIs and implementation details of many other
-tools in the Python ecosystem, especially [Flake8](https://github.com/PyCQA/flake8), [Pyflakes](https://github.com/PyCQA/pyflakes),
-[pycodestyle](https://github.com/PyCQA/pycodestyle), [pydocstyle](https://github.com/PyCQA/pydocstyle),
-[pyupgrade](https://github.com/asottile/pyupgrade), and [isort](https://github.com/PyCQA/isort).
+ruff is written in Rust (1.63.0). You'll need to install the [Rust toolchain](https://www.rust-lang.org/tools/install)
+for development.
 
-In some cases, Ruff includes a "direct" Rust port of the corresponding tool.
-We're grateful to the maintainers of these tools for their work, and for all
-the value they've provided to the Python community.
+Assuming you have `cargo` installed, you can run:
 
-Ruff's autoformatter is built on a fork of Rome's [`rome_formatter`](https://github.com/rome/tools/tree/main/crates/rome_formatter),
-and again draws on both the APIs and implementation details of [Rome](https://github.com/rome/tools),
-[Prettier](https://github.com/prettier/prettier), and [Black](https://github.com/psf/black).
+```shell
+cargo run resources/test/fixtures
+cargo fmt
+cargo clippy
+cargo test
+```
 
-Ruff is also influenced by a number of tools outside the Python ecosystem, like
-[Clippy](https://github.com/rust-lang/rust-clippy) and [ESLint](https://github.com/eslint/eslint).
+## Deployment
 
-Ruff is the beneficiary of a large number of [contributors](https://github.com/charliermarsh/ruff/graphs/contributors).
+ruff is distributed on [PyPI](https://pypi.org/project/ruff/), and published via [`maturin`](https://github.com/PyO3/maturin).
 
-Ruff is released under the MIT license.
+See: `.github/workflows/release.yaml`.
 
-## Who's Using Ruff?
+## Benchmarking
 
-Ruff is used in a number of major open-source projects, including:
+First, clone [CPython](https://github.com/python/cpython). It's a large and diverse Python codebase,

-# flake8-to-ruff
-
-Convert existing Flake8 configuration files (`setup.cfg`, `tox.ini`, or `.flake8`) for use with
-[Ruff](https://github.com/charliermarsh/ruff).
-
-Generates a Ruff-compatible `pyproject.toml` section.
-
-## Installation and Usage
-
-### Installation
-
-Available as [`flake8-to-ruff`](https://pypi.org/project/flake8-to-ruff/) on PyPI:
-
-```shell
-pip install flake8-to-ruff
-```
-
-### Usage
-
-To run `flake8-to-ruff`:
-
-```shell
-flake8-to-ruff path/to/setup.cfg
-flake8-to-ruff path/to/tox.ini
-flake8-to-ruff path/to/.flake8
-```
-
-`flake8-to-ruff` will print the relevant `pyproject.toml` sections to standard output, like so:
-
-```toml
-[tool.ruff]
-exclude = [
-    '.svn',
-    'CVS',
-    '.bzr',
-    '.hg',
-    '.git',
-    '__pycache__',
-    '.tox',
-    '.idea',
-    '.mypy_cache',
-    '.venv',
-    'node_modules',
-    '_state_machine.py',
-    'test_fstring.py',
-    'bad_coding2.py',
-    'badsyntax_*.py',
-]
-select = [
-    'A',
-    'E',
-    'F',
-    'Q',
-]
-ignore = []
-
-[tool.ruff.flake8-quotes]
-inline-quotes = 'single'
-
-[tool.ruff.pep8-naming]
-ignore-names = [
-    'foo',
-    'bar',
-]
-```
-
-### Plugins
-
-`flake8-to-ruff` will attempt to infer any activated plugins based on the settings provided in your
-configuration file.
-
-For example, if your `.flake8` file includes a `docstring-convention` property, `flake8-to-ruff`
-will enable the appropriate [`flake8-docstrings`](https://pypi.org/project/flake8-docstrings/)
-checks.
-
-Alternatively, you can manually specify plugins on the command-line:
-
-```shell
-flake8-to-ruff path/to/.flake8 --plugin flake8-builtins --plugin flake8-quotes
-```
-
-## Limitations
-
-1. Ruff only supports a subset of the Flake configuration options. `flake8-to-ruff` will warn on and
-   ignore unsupported options in the `.flake8` file (or equivalent). (Similarly, Ruff has a few
-   configuration options that don't exist in Flake8.)
-1. Ruff will omit any rule codes that are unimplemented or unsupported by Ruff, including rule
-   codes from unsupported plugins. (See the [Ruff README](https://github.com/charliermarsh/ruff#user-content-how-does-ruff-compare-to-flake8)
-   for the complete list of supported plugins.)
