+jshint-mode
+=======
+
+A work in progress to integrate jshint into emacs via a node.js server, heavily inspited by Kevin Turners lintnode (https://github.com/keturn/lintnode) much thanks.
+
+Dependencies
+============
+
+node.js (http://nodejs.org/)
+
+Building
+========
+
+    git clone git://github.com/daleharvey/jshint-mode.git
+
+Usage
+=====
+
+To run from the command line:
+
+    $ node jshint-mode.js
+    $ curl --form source="<path/to/my.js" --form=filename="my.js" http://127.0.0.1:3003/jshint
+
+To run within emacs (add this to your .emacs)
+
+     (add-to-list 'load-path "~/lib/jshint-mode")
+     (require 'flymake-jshint)
+     (add-hook 'javascript-mode-hook
+         (lambda () (flymake-mode t)))
+
+You need to start the node server manually
+
+    $ node jshint-mode.js
+
+and then run M-x flymake-mode to turn jshint on and off
