-### How does Ruff's import sorting compare to [`isort`](https://pypi.org/project/isort/)?
-
-Ruff's import sorting is intended to be nearly equivalent to `isort` when used `profile = "black"`.
-(There are some minor differences in how Ruff and isort break ties between similar imports.)
-
-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"]
-```
