+==============================
+GN support in the build system
+==============================
+
+:abbr:`GN (Generated Ninja)` is a third-party build tool used by chromium and
+some related projects that are vendored in mozilla-central. Rather than
+requiring ``GN`` to build or writing our own build definitions for these projects,
+we have support in the build system for translating GN configuration
+files into moz.build files. In most cases these moz.build files will be like any
+others in the tree (except that they shouldn't be modified by hand), however
+those updating vendored code or building on platforms not supported by
+Mozilla automation may need to re-generate these files. This is a per-project
+process, described in dom/media/webrtc/third_party_build/gn-configs/README.md for
+webrtc. As of writing, it is very specific to webrtc, and likely doesn't work as-is
+for other projects.
