 Ruff does not yet support third-party plugins, though a plugin system is within-scope for the

+### 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
+    "I001"
+]
+src = ["src", "tests"]
+
+[tool.ruff.isort]
+known-first-party = ["my_module1", "my_module2"]
+```
+
 ### Does Ruff support NumPy- or Google-style docstrings?
