 # Supported Platforms
 
-GoogleTest requires a codebase and compiler compliant with the C++11 standard or
-newer.
-
-The GoogleTest code is officially supported on the following platforms.
-Operating systems or tools not listed below are community-supported. For
-community-supported platforms, patches that do not complicate the code may be
-considered.
-
-If you notice any problems on your platform, please file an issue on the
-[GoogleTest GitHub Issue Tracker](https://github.com/google/googletest/issues).
-Pull requests containing fixes are welcome!
-
-### Operating systems
-
-*   Linux
-*   macOS
-*   Windows
-
-### Compilers
-
-*   gcc 5.0+
-*   clang 5.0+
-*   MSVC 2015+
-
-**macOS users:** Xcode 9.3+ provides clang 5.0+.
-
-### Build systems
-
-*   [Bazel](https://bazel.build/)
-*   [CMake](https://cmake.org/)
-
-Bazel is the build system used by the team internally and in tests. CMake is
-supported on a best-effort basis and by the community.
+GoogleTest follows Google's
+[Foundational C++ Support Policy](https://opensource.google/documentation/policies/cplusplus-support).
+See
+[this table](https://github.com/google/oss-policies-info/blob/main/foundational-cxx-support-matrix.md)

+{: .callout .note}
+NOTE: In the example below, we assume Clang or GCC and set `--cxxopt=-std=c++14`
+to ensure that GoogleTest is compiled as C++14 instead of the compiler's default
+setting (which could be C++11). For MSVC, the equivalent would be
+`--cxxopt=/std:c++14`. See [Supported Platforms](platforms.md) for more details
+on supported language versions.

 Now you can build and run your test:
