+
+## Operating systems and CPUs
+
+The list of officially supported operating systems and CPUs is:
+
+* Android: armeabi-v7a, arm64-v8a, x86, x86_64.
+* iOS: arm64, x86_64.
+* Linux: armeabi-v7a, arm64-v8a, x86, x86_64.
+* macOS: x86_64, arm64 (M1).
+* Windows: x86_64.
+
+Other platforms are not officially supported (which means there is no CI
+coverage for them) but patches to keep WebRTC working with them are welcomed
+by the WebRTC Team.
+
+## Compilers
+
+WebRTC officially supports clang on all the supported platforms. The clang
+version officially supported is the one used by Chromium (hence the version
+is really close to Tip of Tree and can be checked [here](https://source.chromium.org/chromium/chromium/src/+/main:tools/clang/scripts/update.py)
+by looking at the value of `CLANG_REVISION`).
+
+See also [here](https://source.chromium.org/chromium/chromium/src/+/main:docs/clang.md)
+for some clang related documentation from Chromium.
+
+MSVC is also supported at version VS 2019 16.61.
+
+Other compilers are not officially supported (which means there is no CI
+coverage for them) but patches to keep WebRTC working with them are welcomed
+by the WebRTC Team.
