-# Overview
-
-NOTE: This file requires more content.
-
-Since Python 3.8.2, releases have been made through the Microsoft Store
-to allow easy installation on Windows 10.0.17763.0 and later.
-
-# Building
-
-To build the store package, the PC/layout script should be used.
-Execute the directory with the build of Python to package, and pass
-"-h" for full command-line options.
-
-To sideload test builds, you will need a local certificate.
-Instructions are available at
-https://docs.microsoft.com/windows/uwp/packaging/create-certificate-package-signing.
-
-After exporting your certificate, you will need the subject name and
-SHA256 hash. The `certutil -dump <cert file>` command will display this
-information.
-
-To build for sideloading, use these commands in PowerShell:
-
-```
-$env:APPX_DATA_PUBLISHER=<your certificate subject name>
-$env:APPX_DATA_SHA256=<your certificate SHA256>
-$env:SigningCertificateFile=<your certificate file>
-
-python PC/layout --copy <layout directory> --include-appxmanifest
-Tools/msi/make_appx.ps1 <layout directory> python.msix -sign
-
-Add-AppxPackage python.msix
-```
-
-(Note that only the last command requires PowerShell, and the others
-can be used from Command Prompt. You can also double-click to install
-the final package.)
-
-To build for publishing to the Store, use these commands:
-
-```
-$env:APPX_DATA_PUBLISHER = $null
-$env:APPX_DATA_SHA256 = $null
-
-python PC/layout --copy <layout directory> --preset-appxmanifest --precompile
-Tools/msi/make_appx.ps1 <layout directory> python.msix
-```
-
-Note that this package cannot be installed locally. It may only be
-added to a submission for the store.
-
-
-# Submission Metadata
-
-This file contains the text that we use to fill out the store listing
-for the Microsoft Store. It needs to be entered manually when creating
-a new submission via the dashboard at
-https://partner.microsoft.com/dashboard.
-
-We keep it here for convenience and to allow it to be updated via pull
-requests.

-## Title
-
-Python 3.8
-
-## Short Title
-
-Python
-
-## Description
-
-Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.
-
-The Python interpreter and the extensive standard library are freely available in source or binary form for all major platforms from the Python Web site, https://www.python.org/, and may be freely distributed. The same site also contains distributions of and pointers to many free third party Python modules, programs and tools, and additional documentation.
-
-The Python interpreter is easily extended with new functions and data types implemented in C or C++ (or other languages callable from C). Python is also suitable as an extension language for customizable applications.
-
-## ShortDescription
-
-The Python 3.8 interpreter and runtime.
