+# Using HAML-JS with Sprockets and Rails 3.1
+
+Rails 3.1 uses sprockets for its asset pipeline. Rails 3.1 has shown considerable love for SCSS and SASS but has left [HAML] out. We at [Dharana Software Innovations][] are die hard HAML fans. We beleive that it is the best templating language around. So we would like to have it as a part of our client side toolkit as well. The [haml-js] project does exactly that. It was written for Node.js but works well with the browser too.
+
+The gem includes [haml-js]. You would not have to download it separately. To use this gem, you need to do the following. 
+
+In the `Gemfile`, add the following line.
+
+    gem "haml-sprockets"
+
+In `app/assets/javascripts/application.js` add the following line before `//= require_tree .`
+
+    //=require haml
+
+Now, you can create hamljs files under `app/assets/javascripts/templates` folder. You can create the templates folder, if it does not already exist.
+
+    // code for app/assets/javascripts/templates/hello.jst.hamljs
+    %h1 Hello HAML
+
+You can now access the template anywhere in your javascript or coffeescript code.
+
+    JST["templates/hello"]()
+
+This should give you back the string `"<h1>Hello HAML</h1>"`.
