+# Contributing to Ruff
+
+Welcome! We're happy to have you here. Thank you in advance for your contribution to Ruff.
+
+## The basics
+
+Ruff welcomes contributions in the form of Pull Requests. For small changes (e.g., bug fixes), feel
+free to submit a PR. For larger changes (e.g., new lint rules, new functionality, new configuration
+options), consider submitting an [Issue](https://github.com/charliermarsh/ruff/issues) outlining
+your proposed change.
+
+If you're looking for a place to start, we recommend implementing a new lint rule (see:
+[_Adding a new lint rule_](#example-adding-a-new-lint-rule), which will allow you to learn from and
+pattern-match against the examples in the existing codebase. Many lint rules are inspired by
+existing Python plugins, which can be used as a reference implementation.
+
+As a concrete example: consider taking on one of the rules in [`flake8-simplify`](https://github.com/charliermarsh/ruff/issues/998),
+and looking to the originating [Python source](https://github.com/MartinThoma/flake8-simplify) for
+guidance.
+
+### Prerequisites
+
+Ruff is written in Rust. 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:
+
+```shell
+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:
+
+```shell
+cargo +nightly fmt --all     # Auto-formatting...
+cargo +nightly clippy --all  # Linting...
+cargo +nightly test --all    # 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.
+
+Your Pull Request will be reviewed by a maintainer, which may involve a few rounds of iteration
+prior to merging.
+
+### Example: Adding a new lint rule
+
+There are four phases to adding a new lint rule:
+
+1. Define the violation struct in `src/violations.rs` (e.g., `ModuleImportNotAtTopOfFile`).
+2. Map the violation struct to a rule code in `src/registry.rs` (e.g., `E402`).
+3. Define the logic for triggering the violation in `src/checkers/ast.rs` (for AST-based checks),
+   `src/checkers/tokens.rs` (for token-based checks), or `src/checkers/lines.rs` (for text-based checks).
+4. Add a test fixture.
+5. Update the generated files (documentation and generated code).
+
+To define the violation, open up `src/violations.rs`, and define a new struct using the
+`define_violation!` macro. There are plenty of examples in that file, so feel free to pattern-match
+against the existing structs.
+
+To trigger the violation, you'll likely want to augment the logic in `src/checkers/ast.rs`, which
+defines the Python AST visitor, responsible for iterating over the abstract syntax tree and
+collecting diagnostics as it goes.
+
+If you need to inspect the AST, you can run `cargo +nightly 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/[origin]`, named to match
+the code you defined earlier (e.g., `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.
+
+Run `cargo +nightly dev generate-all` to generate the code for your new fixture. Then run Ruff
+locally with (e.g.) `cargo run 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 `src/[origin]/mod.rs` file. Then, run `cargo test --all`.
+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 +nightly dev generate-all`.
+
+### Example: Adding a new configuration option
+
+Ruff's user-facing settings live in a few different places.
+
+First, the command-line options are defined via the `Cli` struct in `src/cli.rs`.
+
+Second, the `pyproject.toml` options are defined in `src/settings/options.rs` (via the `Options`
+struct), `src/settings/configuration.rs` (via the `Configuration` struct), and `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 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., `_`).
+
+Note that plugin-specific configuration options are defined in their own modules (e.g.,
+`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 `flake8_to_ruff/src/converter.rs`.
+
+Finally, regenerate the documentation and generated code with `cargo +nightly dev generate-all`.
+
+## Release process
+
+As of now, Ruff has an ad hoc release process: releases are cut with high frequency via GitHub
+Actions, which automatically generates the appropriate wheels across architectures and publishes
+them to [PyPI](https://pypi.org/project/ruff/).
+
+Ruff follows the [semver](https://semver.org/) versioning standard. However, as pre-1.0 software,
+even patch releases may contain [non-backwards-compatible changes](https://semver.org/#spec-item-4).

-
-You'll also need [Insta](https://insta.rs/docs/) to update snapshot tests:

-
-```shell
-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:
-
-```shell
-cargo +nightly fmt --all     # Auto-formatting...
-cargo +nightly clippy --all  # Linting...
-cargo +nightly test --all    # Testing...
-```
-

-will save you time and expedite the merge process.
-
-Your Pull Request will be reviewed by a maintainer, which may involve a few rounds of iteration
-prior to merging.
-
-### Example: Adding a new lint rule
-
-There are four phases to adding a new lint rule:
-
-1. Define the rule in `src/checks.rs`.
-2. Define the _logic_ for triggering the rule in `src/checkers/ast.rs` (for AST-based checks),
-   `src/checkers/tokens.rs` (for token-based checks), or `src/checkers/lines.rs` (for text-based checks).
-3. Add a test fixture.
-4. Update the generated files (documentation and generated code).
-
-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 rule, you'll likely want to augment the logic in `src/check_ast.rs`, which defines
-the Python AST visitor, responsible for iterating over the abstract syntax tree and collecting
-lint-rule violations as it goes. If you need to inspect the AST, you can run
-`cargo +nightly 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 --no-cache`. Once you're satisfied with the
-output, codify the behavior as a snapshot test by adding a new `testcase` macro to the `mod tests`
-section of `src/linter.rs`, like so:
-
-```rust
-#[test_case(CheckCode::A001, Path::new("A001.py"); "A001")]
-...
-```
-
-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 +nightly dev generate-all`.
-
-### Example: Adding a new configuration option
-
-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.
-
-Ultimately, these two sources of configuration are merged into the `Settings` struct defined
-in `src/settings.rs`, which is then threaded through the codebase.
-
-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., `_`).
-
-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
-responsible for converting `flake8` configuration files to Ruff's TOML format. This logic
-lives in `flake8_to_ruff/src/converter.rs`.
-
-Finally, regenerate the documentation and generated code with `cargo +nightly dev generate-all`.
-

-
-As of now, Ruff has an ad hoc release process: releases are cut with high frequency via GitHub
-Actions, which automatically generates the appropriate wheels across architectures and publishes
-them to [PyPI](https://pypi.org/project/ruff/).
-
-Ruff follows the [semver](https://semver.org/) versioning standard. However, as pre-1.0 software,
