+Supported Versions
+==================
+
+Python Versions
+---------------
+
+Python Apple Support currently supports Python versions 3.9 to 3.14, inclusive.
+
+Operating Systems
+-----------------
+
+The binaries support x86_64 and arm64 for macOS; arm64 for iOS and appleTV devices; arm64_32 for watchOS devices; and arm64 for visionOS devices. It also supports device simulators on both x86_64 and M1 hardware, except for visionOS, for which x86_64 simulators are officially unsupported. This should enable the code to run on:
+
+- macOS 11 (Big Sur) or later, on:
+
+  - MacBook (including MacBooks using Apple Silicon)
+  - iMac (including iMacs using Apple Silicon)
+  - Mac Mini (including Apple Silicon Mac minis)
+  - Mac Studio (all models)
+  - Mac Pro (all models)

+======================
+How This Project Works
+======================
+
+Python Apple Support works by downloading, patching, and building a fat binary
+of Python and selected pre-requisites, and packaging them as frameworks that can be
+incorporated into an Xcode project. The binary modules in the Python standard
+library are distributed as binaries that can be dynamically loaded at runtime.
+
+The macOS package is a re-bundling of the official macOS binary, modified so that
+it is relocatable, with the IDLE, Tkinter and turtle packages removed, and the
+App Store compliance patch applied.
+
+The iOS, tvOS, watchOS, and visionOS packages compiled by this project use the
+official `PEP 730 <https://peps.python.org/pep-0730/>`__ code that is part of
+Python 3.13 to provide iOS support; the relevant patches have been backported
+to 3.9-3.12. Additional patches have been applied to add tvOS, watchOS, and
+visionOS support.
