Project requirements
Download Git
We recommend downloading Git from http://git-scm.com/downloads
Download Composer
Run this in your terminal to get the latest Composer version:
curl -sS https://getcomposer.org/installer | php
Or if you don't have curl:
php -r "readfile('https://getcomposer.org/installer');" | php
This installer script will simply check some php.ini settings, warn you if they are set incorrectly, and then download the latest composer.phar in the current directory
You can run this terminal command to make Composer easily accessible, from anywhere on your system:
mv composer.phar /usr/local/bin/composer
