Setting long_description_content_type to 'text/markdown' causes the prepended RST-style header on lines 23-25 (long_description = '===========\n' + 'OpenFermion\n' + '===========\n\n') to be parsed as a Markdown H1 header. Since README.md already contains a # OpenFermion header, this results in a duplicate title rendering on PyPI.

To fix this, please update lines 23-25 to read the file directly without prepending the redundant header:

with open('README.md', 'r', encoding='utf-8') as readme:
    long_description = readme.read()

python_requires='>=3.10.0',
install_requires=requirements,
extras_require={'resources': resource_requirements},
