+Python version and Source Code Formatting
+-----------------------------------------
+
+The current minimum version of Python required is documented in the :doc:`GettingStarted`
+section. Python code in the LLVM repository should only use language features
+available in this version of Python.
+
+The Python code within the LLVM repository should adhere to the formatting guidelines
+outlined in `PEP-8 <https://peps.python.org/pep-0008/>`_.
+
+For consistency and to limit churn, code should be automatically formatted with the
+`black <https://github.com/psf/black>`_ utility. Black allows changing the formatting
+rules based on major version. In order to avoid unecessary churn in the formatting rules
+we currently use black version 23.x in LLVM.
