@@ -10,4 +10,27 @@ For now, you can install the envjs gem by installing Johnson:
 
   gem install envjs
 
+The envjs gem provides the envjsrb command, which functions as an extended version of the Johnson javascript shell. For example:
+
+mbp:env-js smparkes$ envjsrb
+js> this
+=> [object Window 0]
+js> window.location
+=> about:blank
+js> document.innerHTML
+=> "<html><head><title></title></head><body></body></html>"
+js> 
+
+It's also possible to embed the envjs interpreter similar to the way it's done in Johnson, e.g.,
+
+require 'rubygems' # if necessary
+require 'johnson/tramonkey'
+require 'envjs/runtime'
+
+envjs = Johnson::Runtime.new
+envjs.extend Envjs::Runtime
+window = envjs.evaluate("")
+puts window.location.to_s # == "about:blank"
+puts window.document.innerHTML # == "<html><head><title></title></head><body></body></html>"
