+To trigger the rule, 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

 `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`

 ### 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.
+Ruff's user-facing settings live in a few different places.

-Ultimately, these two sources of configuration are merged into the `Settings` struct defined
-in `src/settings.rs`, which is then threaded through the codebase.
+First, the command-line options are defined via the `Cli` struct in `src/cli.rs`.

-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., `_`).
+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.

-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`.
+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

 ### Do I need to install Rust to use Ruff?

@@ -1397,85 +1485,35 @@ Found 3 error(s).

 ### Does Ruff support NumPy- or Google-style docstrings?

-Yes! To enable a specific docstring convention, start by enabling all `pydocstyle` error codes, and
-then selectively disabling based on your [preferred convention](https://www.pydocstyle.org/en/latest/error_codes.html#default-conventions).
+Yes! To enable specific docstring convention, add the following to your `pyproject.toml`:

-For example, if you're coming from `flake8-docstrings`, the following configuration is equivalent to
-`--docstring-convention=numpy`:
+```toml
+[tool.ruff.pydocstyle]
+convention = "google"  # Accepts: "google", "numpy", or "pep257".
+```
+
+For example, if you're coming from `flake8-docstrings`, and your originating configuration uses
+`--docstring-convention=numpy`, you'd instead set `convention = "numpy"` in your `pyproject.toml`,
+as above.
+
+Alongside `convention`, you'll want to explicitly enable the `D` error code class, like so:

 ```toml
 [tool.ruff]
-extend-select = ["D"]
-extend-ignore = [
-    "D107",
-    "D203",
-    "D212",
-    "D213",
-    "D402",
-    "D413",
-    "D415",
-    "D416",
-    "D417",
+select = [
+    "D",
 ]
-```

-Similarly, the following is equivalent to `--docstring-convention=google`:
-
-```toml
-[tool.ruff]
-extend-select = ["D"]
-extend-ignore = [
-    "D203",
-    "D204",
-    "D213",
-    "D215",
-    "D400",
-    "D404",
-    "D406",
-    "D407",
-    "D408",
-    "D409",
-    "D413",
-]
-```
-
-Similarly, the following is equivalent to `--docstring-convention=pep8`:
-
-```toml
-[tool.ruff]
-extend-select = ["D"]
-extend-ignore = [
-    "D203",
-    "D212",
-    "D213",
-    "D214",
-    "D215",
-    "D404",
-    "D405",
-    "D406",
-    "D407",
-    "D408",
-    "D409",
-    "D410",
-    "D411",
-    "D413",
-    "D415",
-    "D416",
-    "D417",
-]
-```
-
-Note that Ruff _also_ supports a [`convention`](#convention) setting:
-
-```toml
 [tool.ruff.pydocstyle]
 convention = "google"
 ```

-However, this setting is purely used to implement robust detection of Google and NumPy-style
-sections, and thus avoid the [false negatives](https://github.com/PyCQA/pydocstyle/issues/459) seen
-in `pydocstyle`; it does not affect which errors are enabled, which is driven by the `select` and
-`ignore` settings, as described above.
+Setting a `convention` force-disables any rules that are incompatible with that convention, no
+matter how they're provided, which avoids accidental incompatibilities and simplifies configuration.
+
+### How can I tell what settings Ruff is using to check my code?
+
+Run `ruff /path/to/code.py --show-settings` to view the resolved settings for a given file.
