Write Documentation

The scikit-build project could always use more documentation. We welcome help with the official scikit-build docs, in docstrings, or even on blog posts and articles for the web.

Submit Feedback

The best way to send feedback is to file an issue at

If you are proposing a new feature:

  • Explain in detail how it would work.

  • Keep the scope as narrow as possible, to make it easier to implement.

  • Remember that this is a volunteer-driven project, and that contributions are welcome :)

Get Started

Ready to contribute? Here’s how to set up scikit-build for local development.

  1. Fork the scikit-build repo on GitHub.

  2. Clone your fork locally:

    $ git clone

    You can use the gh command line application to do these last two steps, as well.

  3. Make sure you have nox installed using pipx install nox. If you don’t have pipx, you can install it with pip install pipx. (You can install nox with pip instead, but nox is an application, not a library, and applications should always use pipx.) You can install both of these packages from brew on macOS/linux. You can also use pipx run nox instead.

  4. Create a branch for local development:

    $ git checkout -b name-of-your-bugfix-or-feature

    Now you can make your changes locally.

  5. When you’re done making changes, check that your changes pass our linters and the tests:

    $ nox

    If you would like to check all Python versions and you don’t happen to have them all installed locally, you can use the manylinux docker image instead:

    $ docker run –rm -itv $PWD:/src -w /src pipx run nox

  6. Commit your changes and push your branch to GitHub:

    $ git add -u .
    $ git commit -m "Your detailed description of your changes."
    $ git push origin name-of-your-bugfix-or-feature
  7. Submit a pull request through the GitHub website or the gh command line application.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

  1. The pull request should include tests.

  2. If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring, and add the feature to the list in README.rst.

  3. The pull request should work for Python 3.7+ and PyPy. Make sure that the tests pass for all supported Python versions in CI on your PR.


To run a subset of tests:

$ nox -s tests -- tests/

You can build and serve the docs:

$ nox -s docs -- serve

You can build an SDist and a wheel in the dist folder:

$ nox -s build
