h3. What Is The Asset Pipeline?
-With Rails 3.1 comes a new feature known as the asset pipeline. The asset pipeline provides features that have usually been implemented by external gems, such as Jammit and Sprockets. These gems would serve concatenated or compressed versions of the assets of an application, such as stylesheets or JavaScript files so that the number of requests made to the server are reduced, making the page load faster. Rails 3.1 includes the Sprockets gem.
+With Rails 3.1 comes a new feature known as the asset pipeline. The asset pipeline provides features that have usually been implemented by external gems, such as "Jammit":http://documentcloud.github.com/jammit and "Sprockets.":http://getsprockets.org These gems are popular for being able to serve concatenated or compressed versions of the assets of an application, such as Cascade Style Sheets (CSS) or JavaScript (JS) files so that the number of requests made to the server are reduced, making the page load faster. Rails 3.1 includes the Sprockets gem.
h3. How to Use the Asset Pipeline
-In previous versions of Rails, all assets lived under the +public+ directory in directories such as +images+, +javascripts+ and +stylesheets+. With Rails 3.1, the preferred location for these assets is now the +app/assets+ directory. Files in this directory will be served by the Sprockets middleware included in the sprockets gem.

This is not to say that assets can (or should) no longer be placed in +public+. They still can be, they will just be served by the application or the web server which is running the application and served just like normal files. You would only use +app/assets+ if you wish your files to undergo some pre-processing before they are served.
-When a scaffold or controller is generated for the application, Rails will also generate a JavaScript (JS) file (or CoffeeScript if the +coffee-script+ gem is in the +Gemfile+) and a Cascade Style Sheet (CSS) file (or SCSS if +sass-rails+ is in the +Gemfile+) file for that controller. For example, if a +ProjectsController+ is generated, there will be a new file at +app/assets/javascripts/projects.js.coffee+ and another at +app/assets/stylesheets/projects.css.scss+. You should put any JavaScript or CSS unique to a controller inside their respective asset files.

h4. External Assets
-Assets can also come from external sources such as engines. A good example of this is the +jquery-rails+ gem which comes with Rails 3.1 as standard. This gem contains an engine class which inherits from +Rails::Engine+. By doing this, Rails is informed that the directory for this gem may contain assets and the +app/assets+, +lib/assets+ and +vendor/assets+ directories of this engine are added to the search path of Sprockets.
