Asset Organization

1. Pipeline assets can be placed inside an application in one of three locations: app/assets, lib/assets or vendor/assets.

2. app/assets is for assets that are owned by the application, such as custom images, JavaScript files or stylesheets.

3. lib/assets is for your own libraries' code that doesn't really fit into the scope of the application or those libraries which are shared across applications.

4. vendor/assets is for assets that are owned by outside entities, such as code for JavaScript plugins and CSS frameworks.

Search Paths

1. When a file is referenced from a manifest or a helper, Sprockets searches the three default asset locations for it.

2. The default locations are: app/assets/images and the subdirectories javascripts and stylesheets in all three asset locations, but these subdirectories are not special. Any path under assets/* will be searched.
