+Building semver
+===============
+
+.. _PEP 517: https://www.python.org/dev/peps/pep-0517/
+.. _PEP 621: https://www.python.org/dev/peps/pep-0621/
+.. _A Practical Guide to Setuptools and Pyproject.toml: https://godatadriven.com/blog/a-practical-guide-to-setuptools-and-pyproject-toml/

+
+
+This project changed slightly its way how it is built. The reason for this
+was to still support the "traditional" way with :command:`setup.py`,
+but at the same time try out the newer way with :file:`pyproject.toml`.
+Over time, once Python 3.6 gets deprecated, we will support only the newer way.
+
+
+Background information
+----------------------
+
+Skip this section and head over to :ref:`build-pyproject-build` if you just
+want to know how to build semver.
+This section gives some background information how this project is set up.
+
+The traditional way with :command:`setup.py` in this project uses a
+`Declarative config`_. With this approach, the :command:`setup.py` is
+stripped down to its bare minimum and all the metadata is stored in
+:file:`setup.cfg`.
+
+The new :file:`pyproject.toml` contains only information about the build backend, currently setuptools.build_meta. The idea is taken from
+`A Practical Guide to Setuptools and Pyproject.toml`_.
+Setuptools-specific configuration keys as defined in `PEP 621`_ are currently
+not used.
+
+
+.. _build-pyproject-build:
+
+Building with pyproject-build
+-----------------------------
+
+To build semver you need:
+
+* The :mod:`build` module which implements the `PEP 517`_ build
+  frontend.
+  Install it with::
+
+        pip install build
+
+  Some Linux distributions has already packaged it. If you prefer
+  to use the module with your package manager, search for
+  :file:`python-build` or :file:`python3-build` and install it.
+
+* The command :command:`pyproject-build` from the :mod:`build` module.
+
+To build semver, run::
+
+    pyproject-build
+
+After the command is finished, you can find two files in the :file:`dist` folder: a ``.tar.gz`` and a ``.whl`` file.
