 ### Sprockets as a Ruby library
 
@@ -203,6 +203,11 @@ Here's a walkthrough of the installation process:
 
 Once `sprockets-rails` is installed, you can check out Sprockets plugins into the `vendor/sprockets/` directory. By default, `sprockets-rails` configures Sprockets' load path to search `vendor/sprockets/*/src/`, as well as `vendor/plugins/*/javascripts/`. This means that the `javascripts/` directories of Rails plugins are automatically installed into your Sprockets load path.
 
+### Using the bundled Sprockets CGI script
+
+Sprockets comes with a simple CGI script for serving JavaScript outside of a Ruby environment. You can find it, along with brief documentation and installation instructions, as `ext/nph-sprockets.cgi` in your copy of the Sprockets source code. (If you installed Sprockets with RubyGems, you can find the location of the Sprockets source code with the `gem which sprockets` command.)
