It's time to create a real website for this project. I choose to use the Ruby's Ramaze framework which is certainly not the most known Ruby's framework but I found it quite simple to understand and I already used it for previous project.
bundle update
#Assuming user/pass is root
mysql --user=root --password=root
create database psi_rng;
exit;
sequel -m db/migrations mysql2://root:root@localhost/psi_rng
#Don't forget to change your database settings
cp config/database.rb.sample config/database.rb
rackup
rspec
