-CPython source code
-===================
+This document has moved:
 
-This section gives an overview of CPython's code structure and provides
-a summary of file locations for modules and built-ins.
+`CPython Source Code <https://github.com/python/cpython/blob/main/InternalDocs/repo_structure.md>`_.
 
-
-Source code layout
-==================
-
-For a Python :term:`module`, the typical layout is:
-
-* :file:`Lib/{<module>}.py`
-* :file:`Modules/_{<module>}.c` (if there's also a C accelerator module)
-* :file:`Lib/test/test_{<module>}.py`
-* :file:`Doc/library/{<module>}.rst`
-
-For an :term:`extension module`, the typical layout is:
-
-* :file:`Modules/{<module>}module.c`
-* :file:`Lib/test/test_{<module>}.py`
-* :file:`Doc/library/{<module>}.rst`
-
-For :ref:`bltin-types`, the typical layout is:
-
-* :file:`Objects/{<builtin>}object.c`
-* :file:`Lib/test/test_{<builtin>}.py`
-* :cpy-file:`Doc/library/stdtypes.rst`
-
-For :ref:`built-in-funcs`, the typical layout is:
-
-* :cpy-file:`Python/bltinmodule.c`
-* :cpy-file:`Lib/test/test_builtin.py`
-* :cpy-file:`Doc/library/functions.rst`
-
-Some exceptions to these layouts are:
-
-* built-in type ``int`` is at :cpy-file:`Objects/longobject.c`
-* built-in type ``str`` is at :cpy-file:`Objects/unicodeobject.c`
-* built-in module ``sys`` is at :cpy-file:`Python/sysmodule.c`
-* built-in module ``marshal`` is at :cpy-file:`Python/marshal.c`
-* Windows-only module ``winreg`` is at :cpy-file:`PC/winreg.c`
