You need :

• PHP 5.5
• Distribution based on Linux. (don't work with windows!)

To install a new project working with Glial :

install composer

$ curl -sS https://getcomposer.org/installer | php

$ mv composer.phar /usr/local/bin/composer

install a new project (install in current directory, will create a new dir)

$ composer create-project --keep-vcs glial/new-project:5.1.21 --prefer-dist my_glial_project

./install

You are ready to work !
