 ## Basics
 
-Libraries are managed by the `lithium\core\Libraries` class, which handles auto-loading, service location, and introspecting available classes. When loading classes, Lithium assumes a [PSR-0 compatible](http://groups.google.com/group/php-standards/web/psr-0-final-proposal) class mapping structure. For more information, see the [documentation for the `Libraries` class](http://lithify.me/docs/lithium/core/Libraries).

 The default Lithium distribution ships with two `libraries` directories: one located at the root of the distribution, and one located in the `app` folder (or any application you generate with the console tooling). Libraries can be installed into either of these directories, and both are used interchangeably throughout this guide. The global `libraries` directory is intended for libraries which are shared across multiple applications, whereas the local directory is intended for application-specific ones, and will override the global directory in the event of a conflict.

 Pretty straightforward. Using namespaces keeps your application's classes separate from the Lithium core and third-party plugins, allowing for commonly used class names (File, Folder, etc.) to be used in both places.
 
-Lithium classes also follow the [PHP Standards Working Group namespace standard](http://groups.google.com/group/php-standards/web/psr-0-final-proposal) in order allow for easy autoloading of class file, and cross-library interoperability. This keeps your class files clean from messy include statements.
