+Appveyor official support was dropped in cibuildwheel v3.0, due to a lack of CI credits. However, it can probably still be used as-is. Check the Appveyor example from the cibuildwheel v2.0 branch: [appveyor-minimal.yml](https://github.com/pypa/cibuildwheel/blob/v2.23.3/examples/appveyor-minimal.yml).

 Once you've got the wheel building successfully, you might want to set up [testing](options.md#test-command) or [automatic releases to PyPI](deliver-to-pypi.md#automatic-method).
