+# Get at available assets in loaded gems in Sprockets
+
+Either get the list of asset paths:
+
+``` ruby
+require 'sprockets-vendor_gems'
+
+env = Sprockets::Environment.new('.')
+Sprockets.find_gem_vendor_paths(:for => :javascript).each do |path|
+  env.append_path path
+end
+```
+
+or get an Environment with those paths in there already:
+``` ruby
+require 'sprockets-vendor_gems'
+
+env = Sprockets::EnvironmentWithVendoredGems.new('.')
+```
+
+Yeah!
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+    gem 'sprockets-vendor_gems'
+
+And then execute:
+
+    $ bundle
+
+Or install it yourself as:
+
+    $ gem install sprockets-vendor_gems
+
