The installation is complex and will be sorted out later.
After pulling, it is always a good idea to run
php artisan dump-autoload
php artisan migrate
php artisan db:seed
For now, you must have a webserver running as jr.glo.lan
Install node.js from http://nodejs.org/
From the command line run (in the root of the cloned repository):
npm install jquery
and
npm install socket.io
then run:
node server.js
