Description: 

Composer is a dependency management tool for PHP which Drupal 8 has adopted it to handle its PHP dependencies, such as Symfony and Twig. You will find composer.json available at /composer.json, which follows a schema in order to define the version dependencies for each required package.

Installation

To install Composer, you can install Drush Composer using the follwing command:

drush dl composer

Alternatively, you can install Composer using straight-up PHP:

curl -s https://getcomposer.org/installer | php

Usage

Once you have Composer installed, you can update /composer.json accordingly, and run:

cd core
drush composer update

Composer will retrieve new package information and update all the dependencies.
