The source code for a Symfony2.5 Tutorial I followed.
###Install instructions This repository isn't designed to be used by others but in case you want to.
first of all run (php)composer(.phar) update
This ensures you have all the correct dependencies.
when that is ready do the following:
copy and rename /app/config/parameters.yml.dist to /app/config/parameters.yml.
in there edit the database settings to the settings you have locally.
As well as the correct mailer options.
