Sphinx makes it easy to create intelligent and beautiful documentation.

Here are some of Sphinx’s major features:

• Output formats: HTML (including Windows HTML Help), LaTeX (for printable PDF versions), ePub, Texinfo, manual pages, plain text
• Extensive cross-references: semantic markup and automatic links for functions, classes, citations, glossary terms and similar pieces of information
• Hierarchical structure: easy definition of a document tree, with automatic links to siblings, parents and children
• Automatic indices: general index as well as a language-specific module indices
• Code handling: automatic highlighting using the Pygments highlighter
• Extensions: automatic testing of code snippets, inclusion of docstrings from Python modules (API docs) via built-in extensions, and much more functionality via third-party extensions.
• Themes: modify the look and feel of outputs via creating themes, and re-use many third-party themes.
• Contributed extensions: dozens of extensions contributed by users; most of them installable from PyPI.

Sphinx uses the reStructuredText markup language by default, and can read MyST markdown via third-party extensions. Both of these are powerful and straightforward to use, and have functionality for complex documentation and publishing workflows. They both build upon Docutils to parse and write documents.
