 # Initjs
 
-TODO: Write a gem description
+Init.js is a Ruby Gem that helps run your javascript only in a page that its necessary.
 
+Along with Rails, you can make a good structure for your javascript.
+A good example is using the Backbone.js, separating each page into a view of the Backbone.js.
+
+Works fine with Turbolinks from Rails.
+
+
+## Javascript structure example
+
+The structure you need follow is the same of your controller and action.
+You can use a namespace too.
+
+### With Backbone.js
+
+```javascript
+App.Posts.New = Backbone.View.extend({
+  initialize: function() {
+    // Javascript for the page "posts/new"
+  }
+});
+
+App.Posts.Show = Backbone.View.extend({
+  initialize: function() {
+    // Javascript for the page "posts/1"
+  }
+});
+
+// with namespace
+App.Blog.Posts.Show = Backbone.View.extend({
+  initialize: function() {
+    // Javascript for the page "blog/posts/1"
+  }
+});
+```
+
+### Without Backbone.js
+
+```javascript
+App.Posts.New = function() {
+  // Javascript for the page "posts/new"
+};
+
+App.Posts.Show = function() {
+  // Javascript for the page "posts/1"
+};
+
+// with namespace
+App.Blog.Posts.Show = function() {
+  // Javascript for the page "blog/posts/1"
+};
+```
+
+
 ## Installation
 
 Add this line to your application's Gemfile:
 
     gem 'initjs'
 
 And then execute:
 
     $ bundle
 
-Or install it yourself as:
+Run the generator:
 
-    $ gem install initjs
+    rails generate initjs
 
+Add `//= require init.js` to your Javascript manifest file (usually found at `app/assets/javascripts/application.js`).
+
+
+
 ## Usage
 
-TODO: Write usage instructions here
+Include the Initjs tag in your application layout (usually found at `app/view/layouts/application.html.erb`) after the body tag.
+
+```erb
+<%= initjs_tag %>
+```
+
+### The app.js
+
+If you have a commom javascript that you need execute every page, you can put in `app/assets/javascripts/app.js.coffee`
+
+#### Structure example
+
+```coffee
+App = window.App =
+  Common:
+    init: ->
+      # Something here
+    finish: ->
+      # Something here
+```
+
+
+## Work left to do
+
+* Add proper unit tests
