Easily Install Drush with a Phar
Composer has helped quite a lot in the area of installation and dependency management for Drupal and Drush; however, users who want to get a quick start with Drush are sometimes put off by the Composer-based install. As of the Drush 8.0.0-rc3 release, it is now possible to install Drush using a phar. This requires fewer steps than the previous method.
