js/README.md

+This directory contains Protocol Buffer support for JavaScript.  This code works
+in browsers and in Node.js.
+
+The packaging work for this is still in-progress.  For now you can just run the
+tests.  First you need to build the main C++ distribution because the code
+generator for JavaScript is written in C++:
+
+   $ ./autogen.sh
+   $ ./configure
+   $ make
+
+Then you can run the JavaScript tests in this directory:
+
+   $ cd js && gulp test
