+Ruff's linter draws on both the APIs and implementation details of many other
+tools in the Python ecosystem, especially [Flake8](https://github.com/PyCQA/flake8), [Pyflakes](https://github.com/PyCQA/pyflakes),
+[pycodestyle](https://github.com/PyCQA/pycodestyle), [pydocstyle](https://github.com/PyCQA/pydocstyle),
+[pyupgrade](https://github.com/asottile/pyupgrade), and [isort](https://github.com/PyCQA/isort).
+
+In some cases, Ruff includes a "direct" Rust port of the corresponding tool.
+We're grateful to the maintainers of these tools for their work, and for all
+the value they've provided to the Python community.
+
+Ruff's autoformatter is built on a fork of Rome's [`rome_formatter`](https://github.com/rome/tools/tree/main/crates/rome_formatter),
+and again draws on both the APIs and implementation details of [Rome](https://github.com/rome/tools),
+[Prettier](https://github.com/prettier/prettier), and [Black](https://github.com/psf/black).
+
+Ruff is also influenced by a number of tools outside the Python ecosystem, like
+[Clippy](https://github.com/rust-lang/rust-clippy) and [ESLint](https://github.com/eslint/eslint).
+
+Ruff is released under the MIT license.
