Composer Cheat Sheet

Composer is a dependency management tool for PHP 5.3+. It allows you to declare the libraries your project depends on, and it will install them for you in your project. Composer is not a package manager.

For all composer commands you install, you may need to use php composer.phar in the composer installation folder instead of the regular composer.
