 A simple, correct `Python packaging <https://packaging.python.org/>`_ **build frontend**.
 
-build reads your project's `pyproject.toml configuration file <https://packaging.python.org/en/latest/specifications/pyproject-toml/>`_ and invokes **build backends** to create `distribution packages <https://packaging.python.org/en/latest/glossary/#term-Distribution-Package>`_—the files you upload to `PyPI <https://pypi.org/>`_ or install with pip. It focuses solely on building packages and does not manage dependencies or virtual environments.

-Mission Statement
-=================
+*******************
+ Mission Statement
+*******************
 
-Many Python tools combine multiple capabilities into one project. For example, pip_ both installs packages and can build them. While convenient, this tight coupling isn't always desirable. Some users need standalone build tools for custom environments (outside PyPI_), or they manage packages themselves (like Linux distributions do).

-This project fills that gap by providing a standalone build tool following modern Python packaging standards for how build tools communicate with backends and how ``pyproject.toml`` defines build requirements.

 We keep dependencies minimal to make build easy to install and use in restricted environments.
 
-Differences from other tools
-=============================
+******************************
+ Differences from other tools
+******************************
 
-Thanks to standardization, all compliant build frontends produce the same outputs (`source distributions <https://packaging.python.org/en/latest/specifications/source-distribution-format/>`_ and `wheels <https://packaging.python.org/en/latest/specifications/binary-distribution-format/>`_) from the same project. The differences are mainly in scope, dependencies, and extra features.

+differences are mainly in scope, dependencies, and extra features.
 
 ``uv build``
-------------
+============
 
-`uv build <https://docs.astral.sh/uv/>`_ is essentially equivalent to ``python -m build --installer=uv``. Both follow packaging standards. build offers features like ``--config-json`` for passing complex nested configuration to backends, and the pip installer works on systems that don't have pre-compiled uv wheels.

 ``setup.py sdist bdist_wheel``
--------------------------------
+==============================
 
-build is the modern equivalent of ``setup.py sdist bdist_wheel``, supporting any backend — not just `setuptools <https://setuptools.pypa.io/>`_.

 ``hatch build``
----------------
+===============
 
-`hatch build <https://hatch.pypa.io/>`_ is the build command from the Hatch project management tool. It provides a convenient wrapper around the build process as part of the larger Hatch ecosystem for managing Python projects, while build is a standalone tool focused solely on building.

 ``flit build``
---------------
+==============
 
-`flit build <https://flit.pypa.io/>`_ is the build command from the Flit project. One important difference: flit-core produces slightly different source distributions when built by flit itself compared to other frontends. Using build (or any standards-compliant frontend) ensures consistent outputs regardless of the backend.

 ``cibuildwheel``
-----------------
+================
 
-`cibuildwheel <https://cibuildwheel.pypa.io/>`_ is a different kind of tool. While build creates a single wheel for the current platform, cibuildwheel orchestrates building wheels across many platforms and Python versions in CI. It actually calls a build frontend (like build or pip) internally for each platform. Use build to create a pure-Python wheel or a single native wheel; use cibuildwheel when you need to produce native wheels for many platforms.
