 ## Supported Rules

+Regardless of the rule's origin, Ruff re-implements every rule in Rust as a first-party feature.
+
 By default, Ruff enables all `E` and `F` error codes, which correspond to those built-in to Flake8.

 The 🛠 emoji indicates that a rule is automatically fixable by the `--fix` command-line option.

+### How does Ruff's import sorting compare to [`isort`](https://pypi.org/project/isort/)?
+
+Ruff's import sorting is intended to be equivalent to `isort` when used `profile = "black"`, and a
+few other settings (`combine_as_imports = true`, `order_by_type = false`, and
+`case_sensitive` = true`).
+
+Like `isort`, Ruff's import sorting is compatible with Black.
+
+Ruff is less configurable than `isort`, but supports the `known-first-party`, `known-third-party`,
+`extra-standard-library`, and `src` settings, like so:
+
+```toml
+[tool.ruff]
+select = [
+    # Pyflakes
+    "F",
+    # Pycodestyle
+    "E",
+    "W",
+    # isort
+    "I"
+]
+src = ["src", "tests"]
+
+[tool.ruff.isort]
+known-first-party = ["my_module1", "my_module2"]
+```
