Quick notes for installation

Create a database in MySQL, in utf8_general_ci
Create a directory on your hard drive, we'll assume it's at $SYMFONY
Go in it cd $SYMFONY
Fork the repo and clone it in $SYMFONY: git clone https://github.com/yourname/netrunnerdb
This creates a directory named netrunnerdb in $SYMFONY. Let's say DOCROOT=$SYMFONY/netrunnerdb.
Go into it.
Install Composer: curl -s http://getcomposer.org/installer | php
Install the vendor libs: php composer.phar install ; at the end of the install, you'll be asked for your database information
Configure your local webserver with a DocumentRoot pointing to $DOCROOT (vhost probably)
Create the tables: php app/console doctrine:schema:update --force
If the above command fails, edit app/config/parameters.yml and try again
Import the data from the latest netrunnerdb-*.sql.gz into MySQL
Point your browser to /web/app_dev.php
