+This directory contains tests for the
+[NativeIO API](https://github.com/TODO/native-io).
+
+## Note on the synchronous APIs
+
+Chrome is currently working with developers to explore the performance
+implications of using NativeIO as an asynchronous Promise-based API from
+WebAssembly.
+
+In order to assess the performance overhead, a baseline is needed. This baseline
+is a synchronous API that can be easily used to port existing database code to
+WebAssembly. The synchronous API is only exposed to dedicated workers.
+
+Until our performance studies are concluded, Chrome has no plans of shipping the
+synchronous API. In other words, there are no plans of adding a new synchronous
+storage API to the Web Platform.
