## Autoloading
For libraries that follow the [PSR-0](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md)
naming standard, Composer generates a `vendor/.composer/autoload.php` file
for autoloading. You can simply include this file and you will get autoloading
for free.

means that we can just start using classes from it, and they will be
autoloaded.

In addition to PSR-0 autoloading, classmap is also supported. This allows
classes to be autoloaded even if they do not conform to PSR-0. See the
[autoload reference](04-schema.md#autoload) for more details.
> **Note:** Composer provides its own autoloader. If you don't want to use
that one, you can just include `vendor/.composer/autoload_namespaces.php`,
which returns an associative array mapping namespaces to directories.
