About Packagist
Packagist is the main composer repository. It aggregates public PHP packages installable with Composer. Put a file named composer.json at the root of your project, containing your project dependencies. Packagist is the default Composer package repository. It lets you find packages and lets Composer know where to get the code from. You can use Composer to manage your project or libraries' dependencies. First of all, you must pick a package name. This is a very important step since it can not change and it should be unique enough to avoid conflicts in the future. The package name consists of a vendor name and a project name joined by a/. The vendor name exists to prevent naming conflicts. The composer.json file should reside at the top of your package's git/svn/ repository and is the way you describe your package to both packagist and composer. New versions of your package are automatically fetched from tags you create in your VCS repository.
