 PREREQUISITES
 -------------
 
-- `node`: This requires Node 0.10.x or greater.
-- [homebrew][] on Mac OS X.  This simplifies the installation of the gRPC C core.
+- `node`: This requires Node 0.12.x or greater.
 
 INSTALL
 -------
- - [Install gRPC Node][]

-NOTE
-----
-This directory has a copy of `helloworld.proto` because it currently depends on
-some Protocol Buffer 2.0 syntax that is deprecated in Protocol Buffer 3.0.
