+# WebRTC coding style guide
+
+## C++
+
+WebRTC follows the [Chromium][chr-style] and [Google][goog-style] C++
+style guides, unless an exception is listed below. In cases where they
+conflict, the Chromium style guide trumps the Google style guide, and
+the exceptions in this file trump them both.
+
+[chr-style]: https://chromium.googlesource.com/chromium/src/+/master/styleguide/c++/c++.md
+[goog-style]: https://google.github.io/styleguide/cppguide.html
+
+### Exceptions
+
+There are no exceptions yet. If and when exceptions are adopted,
+they'll be listed here.
