+# Package `js_runtime`:
+
+This package contains code that is shared between the dart2js compiler and the
+dart2js runtime libraries.
+
+*Important*: all code under the `lib/shared/` must be kept in sync with the
+runtime at all times (in `sdk/lib/_internal/js_runtime/lib/shared`). The
+`test/in_sync_test.dart` test verifies this.
