 # Overview
 
-The PHP SDK 2.0+ is compatible with PHP 7.0 and above. The compatibility with [older versions](http://windows.php.net/downloads/php-sdk/php-sdk-binary-tools-20110915.zip "php-sdk-binary-tools-20110915.zip") is kept, also available from the [legacy branch](https://github.com/Microsoft/php-sdk-binary-tools/tree/legacy). The toolset was significantly revamped. Newer tools are now available, better workflows are now possible. The toolset consists on a mix of the hand written scripts, selected MSYS2 parts and standalone programs. 
+The toolset consists on a mix of the hand written scripts, selected MSYS2 parts and standalone programs. It supports any workflows, be it a custom, local or a CI build whatsoever.
+
+The PHP SDK 2.2+ is compatible with PHP 7.2 and above.
+
+The PHP SDK 2.1 is required to build PHP 7.1 or 7.0.
+
+The legacy binary tools SDK is available from the [legacy branch](https://github.com/php/php-sdk-binary-tools/tree/legacy) and is suitable to build PHP 5.

+# Debugging PHP
+
+This part covers debugging possibilities for the builds produced by the native VS compilers.
+For the cross compiled builds produced with toolsets other than VC++, please check the
+documentation for the corresponding toolsets. In any case, general principles on debugging
+native programs apply.
+
+Either a debug build of PHP or enabled debug symbols are required to be able to debug PHP.
+A debug build is usually more suitable for the development process and can be produced by
+adding `--enable-debug` to the configure options. A release build with debug symbols can
+be produced by adding `--enable-debug-pack`. These options are mutually exclusive.
+
+## Debugging with Visual Studio
+
+- Configure with either `--enable-debug` or `--enable-debug-pack`.
+- A debug build might bring better experience for dev, but sometimes you want to debug a release build.
+- `nmake run ARGS=yourscript.php DEBUGGER=1`, that will open a Visual Studio window.
+- Any additional runtime options for PHP or the script executed go to ARGS, too.
+- Select `Debug -> New Breakpoint -> Function Breakpoint` and add a function where the debugger should break.
+- Click `Start`.
+
+Adding a breakpoint before starting debugging might be not necessary, if a crash is debugged. When such a script runs
+under the debugger, the debugger will stop at the crashing point. In that case, a breakpoint can be added
+around the crashed code directly.
+
+## Debugging test suite with Visual Studio
+
+The [Microsoft Child Process Debugging Power Tool](https://marketplace.visualstudio.com/items?itemName=vsdbgplat.MicrosoftChildProcessDebuggingPowerTool)
+plugin for Visual Studio is required. After installing it, following these steps
+
+- `nmake test TESTS=ext/myext/tests/sometest.phpt DEBUGGER=1`
+- Select `Debug -> Other Debug Targets -> Child Process Debugging Settings` and enable child process debugging.
+- If necessary, add a breakpoint and start debugging as described in the previous section.
+
+## Debugging with WinDbg
+
+PHP can also be debugged with the tools from the WinDbg package. There is currently no way
+implemented in the Makefile to start the WinDbg integrated, so it needs to de done manually.
+Either a debug build or a release build with debug symbols is still required, as described
+previously.

+# Internal notes
 
+## Releases
+
+Users of the PHP SDK are supposed to use tagged versions for stability and
+reproducability.  This requires the maintainers of the PHP SDK to create such
+tags for *all* *relevant* *changes*.  The tag format should be `php-sdk-X.Y.Z`,
+with the common major, minor and revision numbers.
+
+Comprehensive changes, which would be hard to test extensively, such as updates
+to the bundled PHP or the MinGW tools, should walk through a QA (aka. pre-release)
+process, typically with beta versions (e.g. `php-sdk-X.Y.Zbeta1`).  Only after
+these have been thoroughly tested, and all relevant issues have been resolved,
+a GA release should be tagged.
+
+After each tag, a couple of other repositories should be informed about the
+available update, ideally in form of a pull request.  These repositories are:
+
+* https://github.com/php/php-src (for Windows CI)
+* https://github.com/php/php-windows-builder
+* https://github.com/php/setup-php-sdk
